Description _ rkubacki 2004-06-14 17:37:11 UTC

build from Jun 11, Linux, JDK1.5.0b55

Due to problems with thread semantic the progres
indication in find usages dialog can be broken at
any time and the whole AWT event processing can be
blocked. It means no UI updates/repainting. This
is because there can be arbitrary request for MDR
operation called with the AWT thread that will
wait for
org.netbeans.modules.javacore.ExclusiveMutex.enter

For an example see attached thread dump where Jave
editor updates global activated nodes during
computation of usages. As this update goes to the
MDR everything is blocked.

Comment 1 Martin Matula 2004-06-16 00:42:03 UTC

The issue with nodes was fixed. The general issue of blocking AWT
should be fixed by moving the code that accesses the MDR from the AWT
thread. Please file particular cases where it is broken as separate
issues.

Radime, can you verify this issue, please? Thanks.

I agree with Martin that we can close this now
