Description Marian Petras 2006-05-24 14:24:15 UTC

(NetBeans 5.0, Linux / Fedora Core 4, Intel PC, JDK 1.6.0-b84)

A deadlock occured after I asked the IDE to display a diff of the current file.

I right-clicked on the tab of a file (JUnitAntLogger.java) in the editor and
selected CVS|Diff.... A tab labelled "JUnitAntLogger.java [ Diff ]" was opened
and activated, a progress bar with title 'Diffing "JUnitAntLogger.java" ...'
appeared and the IDE froze.

According to the JRE, the freeze was caused by a deadlock:

Found one Java-level deadlock:
=============================
"Default RequestProcessor":
  waiting to lock monitor 0x08fe670c (object 0x8e7432a0, a java.lang.Class),
  which is held by "AWT-EventQueue-1"
"AWT-EventQueue-1":
  waiting to lock monitor 0x08fe6af4 (object 0x86fe45a8, a
org.netbeans.modules.editor.EditorModule$HackMap),
  which is held by "Default RequestProcessor"

I will attach a full thread dump.

I think this is an editor issue, please evaluate.

This should be now fixed after the changes made for fixing issue #92449.
