What steps will reproduce the problem?
Trying to launch the debugger from Eclipse and it doesn't seem to connect :( 
This seems to be happening after installing VJET, before this plugin, it was 
working fine...

What is the expected result?
- Debugger will connect.

What happens instead?
I see Launching delegate... and after a long period of time (maybe 2 minutes), 
i'm getting a 

An internal error occurred during: "Launching New_configuration".
Timeout

If I try again (twice), now I'm getting a:
Failed to connect to Standalone V8 VM
Failed to get version

Please provide any additional information below. If possible, attach a
(reduced) test-case.
- Install eclipse
- Install VJET 
- Try to open a debug instance...

I would like to provide more info but it doesn't seems that I can get some 
stacktrace..any place I can give more info... ?

I have no clue if that help but while it's trying to connect, if I just try to 
refresh a page in chrome (to generate some server activity), I'm getting this 
right away in eclipse:

Timeout is an unrelated effect (see comment #13 at 
http://code.google.com/p/chromedevtools/issues/detail?id=54 for details).

Refreshing or any server activity "pumps" debug requests.

NPE is harmless. We will exterminate it later.

On the first glance VJET may inject its source locator in our launch. Possible 
redirection to them. Needs looking more.

As per
https://github.com/ebayopensource/vjet/blob/master/eclipse/plugins/org.ebayopens
ource.vjet.eclipse.debug/src/org/ebayopensource/vjet/eclipse/internal/debug/Laun
chListener.java
VJET seems to unconditionally update (ruin) our launch:
launchChanged -> setUpSourceLocator
This is probably wrong.
Should redirect issue to them.

This bug is fixed in VJET latest version released today. Please install latest 
version and let me know if you are still having issues.

Earlyster,
I, for one, work based on reading VJET source code. The source code now looks 
correct.
I hope that Abuck.Joe (the reporter of this issue) verifies the new version (or 
in any other way dismisses the issue).
