Description _ rkubacki 2004-06-17 15:03:00 UTC 
dev build from Jun 17, Linux, JDK1.5.0b55

JavaEditor$11 updates set of activated nodes and
uses old source hierarchy. In current dev build
I've seen many stack traces begining with 

org.netbeans.modules.javacore.parser.ResourceInfo.refreshASTree(ResourceInfo.java:48)
org.netbeans.modules.javacore.jmiimpl.javamodel.MetadataElement.getASTree(MetadataElement.java:904)

They slow down the editor a lot.

This inner class really causes a lot of activity. PatternGroupNodes
are created if you move cursor out of class or into some member and
back into it.

Fixed by Honza Pokorsky (see issue 44661).
