Description eleland 2013-05-22 15:48:35 UTC 
I thought I had this problem solved, but I don't.

NetBeans 7.3 IDE hangs when starting. Previously I deleted the "lock" file in the 
C:\Users\<username>\AppData\Roaming\NetBeans\7.3 directory, and then NetBeans would load again.

I've tried that fix and it does not work. NetBeans hangs, just starting up and attempting to load my PHP project.

I have no idea how to solve this problem. The IDE is useless. I am quite amazed that this kind of thing can happen: how can this product simply start up and then just HANG?

I have never seen this before in any IDE. I'm astounded.

Is there a fix or workaround? Guess I have to go back to VisualStudio or Eclipse.
Comment 1 Ondrej Brejla 2013-05-22 15:54:59 UTC 
Sorry, but you are the only one who complains. I can't reproduce that. Can you attach a project, which are opened on startup? Can you provide us a thread dump (use jstack) when the IDE is locked?

You can also try 7.4 dev build - http://bits.netbeans.org/download/trunk/nightly/latest/

And imho it will not be an issue of PHP modules...but hard to say.

Testers, can you look at it? Thanks.

Until more usable info provided, incomplete.
Comment 2 eleland 2013-05-22 18:13:32 UTC 
I don't have jstack. I tried SendSignal but I can't get a PID. Windows Task Manager does not show the PID. I don't think attaching the entire project is an option.

If you have a suggestion how to run SendSignal to get the information, please let me know, or any other suggestion.

I'm sorry to complain. I don't want to complain, I just wanted to use the IDE. It doesn't run, I must be the only person in the world with this problem. Just lucky I guess.

NetBeans 7.3 IDE starts up and hangs.

I don't know if this is a PHP or whatever problem, I'm not a NetBeans developer, just someone who wanted to try to work on a PHP website.

Thanks for your time.

You can try VisualVM as a profiling tool - http://visualvm.java.net

I just see php.project twice in there...but really don't understand this Project code...maybe Tomas can. Tomasi, what do you think? Do you see something strange?
Comment 6 Tomas Mysik 2013-05-24 04:46:10 UTC 
It seems to - I can be wrong, of course - that the problem is in org.netbeans.modules.image.ImageViewer.updateNameInEDT() which calls SwingUtilities.invokeAndWait() - this can easily end with a deadlock. Could you please evaluate?

Thanks.

I thought that, but wasn't sure ;) I'm curious about that.
