Description
When SA is attached to a process using attach(), detached using detach() and then re-attached to the same process using attach(), the second attach() call fails. On Windows, it fails with the following trace: java.lang.RuntimeException: not attached to a process or Dr Watson dump at sun.jvm.hotspot.debugger.windbg.WindbgDebuggerLocal.requireAttach(WindbgDebuggerLocal.java:438) at sun.jvm.hotspot.debugger.windbg.WindbgDebuggerLocal.readBytesFromProcess(WindbgDebuggerLocal.java:484) at sun.jvm.hotspot.debugger.DebuggerBase$Fetcher.fetchPage(DebuggerBase.java:76) at sun.jvm.hotspot.debugger.PageCache.getPage(PageCache.java:178) at sun.jvm.hotspot.debugger.PageCache.getInt(PageCache.java:96) at sun.jvm.hotspot.debugger.DebuggerBase.readCInteger(DebuggerBase.java:355) at sun.jvm.hotspot.debugger.DebuggerBase.readAddressValue(DebuggerBase.java:454) at sun.jvm.hotspot.debugger.windbg.WindbgDebuggerLocal.readAddress(WindbgDebuggerLocal.java:316) at sun.jvm.hotspot.debugger.windbg.WindbgAddress.getAddressAt(WindbgAddress.java:72) at sun.jvm.hotspot.types.basic.BasicField.getAddress(BasicField.java:248) at sun.jvm.hotspot.types.basic.BasicAddressFieldWrapper.getValue(BasicAddressFieldWrapper.java:48) at sun.jvm.hotspot.memory.Universe.getHeapBase(Universe.java:104) at sun.jvm.hotspot.runtime.VM.initialize(VM.java:345) at sun.jvm.hotspot.HotSpotAgent.setupVM(HotSpotAgent.java:420) Caused: sun.jvm.hotspot.debugger.DebuggerException at sun.jvm.hotspot.HotSpotAgent.setupVM(HotSpotAgent.java:424) at sun.jvm.hotspot.HotSpotAgent.go(HotSpotAgent.java:315) at sun.jvm.hotspot.HotSpotAgent.attach(HotSpotAgent.java:158)
