com.ibm.icu.text.MessageFormat initialization maxing out CPU [message #480910]

All of a sudden I'm seeing crazy CPU use and it appears to be due to
com.ibm.icu.text.MessageFormat:
> private static UnicodeSet IDStartChars = new UnicodeSet("[:ID_Start:]");

which is triggered when building an editor action bar, adding a GEF
UndoRetargetAction in this case. I'm not sure what's changed in my app to
cause this (I have a large change set waiting to be checked in.. is there
a history view showing what I've changed eg since 1pm today?!).

I'd have thought that an i18n prob like this might get triggered by a
manifest change, but I don't see any in the sync view.

Has anyone every come across something like this??

Thanks,
Justin

When it starts chewing up the CPU you can get a stack dump to help understand what is taking all of the time. See http://wiki.eclipse.org/How_to_report_a_deadlock
