Description Martin Krauskopf 2005-05-06 15:19:21 UTC 
FC3, JDK 1.5.0_03, custom build from today's morning (050506)

IDE "hangs" from time to time because of 100% CPU usage. It seems it is a
consequence of changes in apisupport (not sure). It didn't happen in 2-3 days
old builds.

It mostly happen when you right click a ModuleProject node (i.e. call its popup
menu) in ProjectExplorer --> 5-15s 100% cpu utilization. Second time it works
ok. After some time it happens again.

Also it happened during opening a new module.

Not sure exactly when it happens --> Random.

Attaching thread dump, which is always (almost) the same when 100% utilization
happend. At least lines around:

at_org.openide.xml.XMLUtil.parse(XMLUtil.java:289)
at_org.netbeans.modules.apisupport.project.ModuleList.parseData(ModuleList.java:484)

Cf. issue #58639. May become WONTFIX.
Comment 3 Jesse Glick 2005-05-06 18:28:01 UTC 
Actually, there is a problem with the caching in ModuleList...investigating.
Comment 4 Jesse Glick 2005-05-06 18:30:14 UTC 
Found it, typo. Would not have made this mistake if we were using -source 1.5
for NB, sigh...
