JDT Debug can not connect/list VM started with suspend=y

    Details

      Description

      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/org.jboss.tools.common.jdt.debug/src/org/jboss/tools/common/jdt/debug/RemoteDebugActivator.java#L171 due to Exception thrown in ToolsCore.getJvmArgs

      Seemingly JVMStat can not connect to a suspended VM.
