Description
Bytecode Escape Analyzer produces incorrect escape information for methods without oop arguments since it do not analyse such methods. For such methods which return an object bcEscapeAnalyzer always says that it return a new non-escaping allocated object since it is default escape information for a method before bytecode analysis. In the failed test cases the methods are accessors for static fields oop (which global escape). And the caller method synchronizing on this field. But locks were removed since EA says it is not escaping. Failed nsk methods: nsk/monitoring/ThreadInfo/getLockName/getlockname001 nsk/monitoring/stress/thread/cmon001 nsk/jdwp/StackFrame/GetValues/getvalues001 nsk/jdwp/StackFrame/SetValues/setvalues001 nsk/jdwp/StackFrame/ThisObject/thisobject001 nsk/jdwp/ThreadReference/CurrentContendedMonitor/curcontmonitor001 nsk/jdwp/ThreadReference/Interrupt/interrupt001 nsk/jdwp/ThreadReference/Name/name001 nsk/jdwp/ThreadReference/OwnedMonitors/ownmonitors001 nsk/jdwp/ThreadReference/Resume/resume001 nsk/jdwp/ThreadReference/Status/status001 nsk/jdwp/ThreadReference/Stop/stop001 nsk/jdwp/ThreadReference/Suspend/suspend001 nsk/jdwp/ThreadReference/SuspendCount/suspendcnt001
