We like to do limited update of Java VisualVM in JDK 7 to address a few critical issues:
1) VisualVM project on java.net was migrated to Kenai and Java VisualVM needs new URL to the plugin center. The old one still works, but it is not clear how long. So we should start using new one ASAP.
2) With release of JDK 7, Java VisualVM needs to address two things to work properly with JDK 7
    a) adapt to the fact that the JDK vendor is now Oracle instead of Sun
    b) fix the issue <http://netbeans.org/bugzilla/show_bug.cgi?id=191297> with the more strict classfile verification in JDK 7 (LocalVariableTypeTable, LocalVariableTable, StackMapTable attributes)
3) Links on welcome screen will be updated to use oracle.com where possible.
This update will be based on Java VisualVM 1.3.2, which were released on March 3rd 2011.
Release notes for VisualVM 1.3.2 are avilable here: <http://visualvm.java.net/relnotes.html>
