Rob Stryker commented on JBIDE-20217:
-------------------------------------
I've made 2 commits to fix the npe on isDebugxxx
https://github.com/jbosstools/jbosstools-server/pull/374
https://github.com/jbosstools/jbosstools-base/pull/451
One is a safety precaution in base, the other is the jvm connection in jmx view being a
bit smarter and saying if the vm we're looking for no longer exists or isn't in
the cache, we won't ask base if its debugable (because it doesn't exist).
Hopefully these fix the issues, though I can't replicate at this time. I'll
resolve this for now, but please re-open if its still present after respin-a.
JDT Debug can not connect/list VM started with suspend=y
--------------------------------------------------------
Key: JBIDE-20217
URL: https://issues.jboss.org/browse/JBIDE-20217
Project: Tools (JBoss Tools)
Issue Type: Bug
Components: common/jst/core
Affects Versions: 4.3.0.Beta1
Reporter: Aslak Knutsen
Assignee: Rob Stryker
Priority: Critical
Labels: new_and_noteworthy
Fix For: 4.3.0.CR1
Having a VM started with suspend=y cause the following error to be logged from
https://github.com/jbosstools/jbosstools-base/blob/master/common/plugins/...
due to Exception thrown in ToolsCore.getJvmArgs
Seemingly JVMStat can not connect to a suspended VM.
