I couldn't reproduce the problem on a Mac machine. The test passed in the subsequent build http://download.eclipse.org/eclipse/downloads/drops/M20111214-1406/testresults/html/org.eclipse.ant.tests.ui_macosx.cocoa.x86_5.0.html. 

There were some 'Program did not suspend' problems as in bug 294321, but the call stack is slightly different. bug 294321 takes care of the problem during launch. This seems to be happening during stepover. 
Mike, Do you think the problems are similar?

> Mike, Do you think the problems are similar?

I reads as similar, the problem with all of the "program did not suspend" failures is that they are timing sensitive - by that I mean if a step / suspend / etc takes too long to respond the debugger times out, which causes these kinds of failures. 

The best way we found to alleviate these kinds of failures is to use the TestAgainException (from the JDT debug tests), which is thrown if a debugger test times out. The failing test is run again a set number of times to double check if it is really a failing tests or a timing issue.
