Build ID: M20080911-1700 Steps To Reproduce: Note: this bug is very similar to Bug 88752, but bug 88752 is reported as "fixed" years ago... I am reliably getting this exception debugging a multithreaded Java app, when "Expressions" window contains some invalid-in-context expressions. I have the following in "Expressions" window (note: Ints.textToString does some new String(), but a and aAddr are invalid at that point anyway). "Ints.textToString(a, aAddr)" "Ints.textToString(b, bAddr)" "a[aAddr>>>2]" "b[bAddr>>2]" More information: eclipse.buildId=M20080911-1700 java.version=1.6.0_07 java.vendor=Sun Microsystems Inc.

Igor/Babu, could you post here testcase (sample project) and reproduction steps?
This will be fixed with bug 277574 *** This bug has been marked as a duplicate of bug 277574 ***
