[jbosstools-issues] [JBoss JIRA] (JBIDE-7783) GWT throws exceptions during Java field rename

    [ https://issues.jboss.org/browse/JBIDE-7783?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12699821#comment-12699821 ] 

Victor Rubezhny commented on JBIDE-7783:
----------------------------------------

Cannot reproduce this CCE in my environment neither using Google Web Toolkit 2.4.0 SDK Bundle for Eclipse 3.7 (which is provided by Nick's Target Platform for Eclipse 3.7), nor by using the GPE project's plug-in built from a latest source. 

Regarding the source code, the line numbers in the stacktrace provided are not correlate with the source code I have. There are the correct checks/type casts present in the latest source of com.google.gwt.eclipse.core.refactoring.GWTRenameParticipant.initialize() method when calculating a new element. 

Also, I cannot reproduce the issue described in http://code.google.com/p/google-web-toolkit/issues/detail?id=4656&can=1&q=refactor&colspec=ID%20Type%20Status%20Owner%20Milestone%20Summary%20Stars, as well as the fix for the BugZilla issue referenced there (https://bugs.eclipse.org/bugs/show_bug.cgi?format=multiple&id=317264) is released for Eclipse 3.6.1 and 3.7. 

So, I suppose that the issue is out-of-date and fixed at least since Google Web Toolkit 2.4.0 SDK Bundle for Eclipse 3.7.
