Description Markus Keller

(At least since 4.3.2.M20140221-1700, but the cause for the problem only became visible with the better exception message from bug 414285 comment 10.)

I had a Foundation1_0 VM in a workspace, and the JRE's default VM arguments were set to "-showversion". This results in the exception below on each startup.

The problem is in AbstractVMInstall#evaluateSystemProperties(..) where the default VM arguments are added to the launch, but the code expects to have total control over the process' output stream.

The fix is either to prevent the addition of default VM args in this case, or to use a different mechanism (e.g. a file) to transfer the output from the VM.

The workaround is to remove the default VM args, restart Eclipse, and then somehow use the VM so that the values can be cached (once and forever...).

This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're closing this bug.

If you have further information on the current state of the bug, please add it and reopen this bug. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.
