Tim Boudreau commented on NETBEANS-373:
---------------------------------------
The root of the problem is here:
[http://hg.openjdk.java.net/jdk/jdk/file/ce86061aff12/src/java.desktop/macosx/classes/sun/lwawt/macosx/CAccessible.java#l102]
What's missing from the stack trace is how CAccessible gets a reference to the
dialog or its contents, since that is missing from the stack trace. Best guess
is some code path through the bowels of the JDK when the dialog's native peer
is created - ?
> Netbeans sometimes freezes when showing any refactor dialog when running with
> jdk 1.8.0_152-b16 or later

> Key: NETBEANS-373
> URL: https://issues.apache.org/jira/browse/NETBEANS-373
> Project: NetBeans
> Issue Type: Bug
> Components: java - Refactoring
> Affects Versions: 8.2, 9.0
> Environment: Mac
> Reporter: Austin Stephens
> Priority: Blocker
>
> Sometimes (or almost always), when you try to do some refactor action,
> NetBeans freezes. It appears that a lock is obtained on a panel when the
> dialog is shown, and the AppKit Thread tries to get the lock while trying to
> add an accessible listener to it.
