It seems that the java module *still* stores EA-OpenIDE-Connection attrs in $userdir/var/attributes.xml (i.e. uses ConnectionSupport). Surely this is not needed any more now that we have MDR and javamodel.
These attrs just keep on accumulating in attributes.xml every time you open a source file that might use them. attributes.xml keeps on getting bigger (until you delete it); I caught mine getting to over 250Kb. And it is slow to read - thread dumps of the IDE freezing for a while sometimes show it trying to load this file.
Should now be fixed by: http://java.netbeans.org/servlets/ReadMsg?list=cvs&msgNo=10942 http://java.netbeans.org/servlets/ReadMsg?list=cvs&msgNo=10945
