Message log with the debug output
I've just got this after Mercurial->Revert ing a java file. Note that i have projects opened from two different netbeans clones (maybe it's relevant).
*** Bug 190758 has been marked as a duplicate of this bug. *** I seem to be able to reproduce consistently (now using DEV 20101005000), but I'm not hitting your logging code. The changeset shows you added the additional logging to getMainMarkForBlockAnnotations, but I'm getting stuck in computeTotalStatus. --- I took a look at o.n.editor.Annotations and found something odd in a changeset for Bug 185466: http://hg.netbeans.org/jet-main/diff/06db14fa2ca8/editor.lib/src/org/netbeans/editor/Annotations.java In two methods, getLineAnnotations(int line) and getNextLineWithAnnotation(int line), the following code was added: 1.52 + if (lastGetLineAnnotationsIdx != -1 && lastGetLineAnnotationsLine != -1 && lastGetLineAnnotationsResult != null) { 1.53 + if (lastGetLineAnnotationsLine == line) { 1.54 + return lastGetLineAnnotationsResult; 1.55 + } else if (lastGetLineAnnotationsLine + 1 == line && lastGetLineAnnotationsIdx + 1 < lineAnnotationsArray.size()) { 1.56 + annos = (LineAnnotations)lineAnnotationsArray.get(lastGetLineAnnotationsIdx + 1); 1.57 + lastGetLineAnnotationsIdx++; 1.58 + lastGetLineAnnotationsLine = annos.getLine(); 1.59 + lastGetLineAnnotationsResult = annos; 1.60 + return annos; 1.61 + } 1.62 + } Per the Javadoc for lineAnnotationsArray, it is ordered by line number. So the 'else if' branch of the nested 'if' will work for the getNextLineWithAnnotation case (as lastGetLineAnnotationsIdx + 1 will be the next possible line with annotations). However, the same logic is used for getLineAnnotations and here I believe it is incorrect. I haven't had a whole lot of time to read all of the code, but it seems to me that the following logic DOES NOT HOLD: if (lastGetLineAnnotationsLine + 1 == requestedLine) { // possible but not always true: assert lineAnnotationsArray.get(lastGetLineAnnotationsIdx + 1).getLine() == requestedLine; } Other code, even in the same method, checks the return from LineAnnotations.getLine(). In the case of the getLineAnnotations method, I don't believe this 'else if' branch should exist; it should probably fall through to the binary search case or at least add a check for a matching getLine() value. (It should be possible to 'seed' the binary search with the lastGetLineAnnotationsXXX information as a micro-optimization instead of always starting between 0 and size()-1.) It's probably unrelated but in a multi-threaded environment it could potentially return incorrect values. Created attachment 102276 [details]
Snapshots of AWT EQ thread at various times after hang, same process
I also noticed that Annotations$LineAnnotations.getLine() reports 0 if for some reason the collection of annotations is empty... this sounds more like the culprit (which would reset your line loop variable back to zero each time it hit that particular LineAnnotations object).
I don't know what the implications would be of changing this behavior (using Integer.MAX_VALUE instead of 0, for instance)... it's probably safer to add a guard condition to your loops to ensure that the condition variable 'line' is always increasing and terminate if the next value is <= last value.

Messages log with debug output from getMainMarkForBlockAnnotations
In an unrelated project/file, I also happened to hit the logging in getMainMarkForBLockAnnotations. Related log messages attached.

Thread dump of hanging netbeans DEV 201010190000
Using DEV 201010190000 I get similar problems as wrprice, netbeans hangs but there is no log message produced.

Thread dump of hang in annotations processing
Attached is thread dump generated from NB 6.9.1 after the IDE froze and the process used all available CPU as if in an infinite loop. Appears it gets into a infinite loop in the AWT EDT.
Steps leading up to crash:
1) did a refactor copy of a .java source file
2) working from bottom of new file upwards
2a) select method body (selection was again done from bottom upwards)
2b) hit delete key
3) after repeating step 2 a few times the IDE sometimes hangs
Got a repeat of this a week later after performing same steps and the stack trace of the AWT-EventQueue-1 thread was identical. I have had the same crash on a few previous occasions before while (from what I can recall) performing these same steps, so there seems to be some measure of repeatability to it.

IDE log
I was told (by NetBeans' log) to update this issue.
Product Version: NetBeans Platform Dev (Build 110223-7d92764348b8)

Thanks for the log. I assume the IDE remained responsive (right?). The Annotations class clearly needs some improvements, but that does not qualify as a P2, IMO (esp. as problems like this seem not to be frequent). (In reply to comment #21) > Thanks for the log. You're welcome, of course. > I assume the IDE remained responsive (right?). Right. My IDE log says that I should add these lines to this issue: WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 WARNING [org.netbeans.modules.editor.errorstripe.AnnotationViewDataImpl]: Please add the following info to https://netbeans.org/bugzilla/show_bug.cgi?id=188843 : line < last: 139 < 161 Product Version: NetBeans IDE 7.0.1 (Build 201107211357) Java: 1.6.0_24;

I will upload the messages.log files I have. I dont remember what I was doing when it hung. I think I had focus in another application. This happened an hour or two after restart of computer (and naturally also restart of netbeans). I was able to work in netbeans for that time. I tried closing netbeans (rightclick->close window). After 5-10 mins it finally closed. During shutdown xdebug notified firefox that debugsession ended. PHP development on win 7 computer. 4 cores, 8 bg ram. Created attachment 150398 [details]

Created attachment 100965 [details] Stack traces from EQ 100721-21c866c159dc. I pressed Ctrl-Z to undo some minor edits in a Java source file. The IDE suddenly froze at 100% CPU and did not recover. Attaching some thread dumps.
