Geertjan Wielenga commented on NETBEANS-373:
--------------------------------------------
Here you're making use of NetBeans IDE 8.2, i.e., this issue is not about
Apache NetBeans. If this issue cannot be reproduced in Apache NetBeans
(incubating) 9.0 Beta, it cannot be a blocker for the release of Apache
NetBeans (incubating) 9.0.
> Netbeans sometimes freezes when showing any refactor dialog when running with
> jdk 1.8.0_152-b16 or later

> 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.
