Just wanted to bring attention to an issue discovered with Sun’s recently released 1.6.0_14 virtual machine. Breakpoints are unreliable - i.e. do not always suspend execution. The problem occurs on Windows and Linux platforms. The associated Eclipse bug is:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=279137
At this point, it appears to be an issue with the VM rather than Eclipse. The workaround is to use the 1.6.0_13 virtual machine.
