Integrated into 'main-golden', will be available in build *201203260401* on http://bits.netbeans.org/dev/nightly/ (upload may still be in progress)
Changeset: http://hg.netbeans.org/main-golden/rev/2aa58a00e3c7
User: Jan Lahoda <jlahoda@netbeans.org>
Log: #210007: ensure that Swing methods are only invoked from AWT, preventing NPE.
