6812971: SA: re-attaching to process fails
Summary: After attaching, de-attaching SA from a process, the second time attach() call fails. This happens because in VM.initialize(), Universe does not get re-initialized before it is accessed.

31 /** <P> This interface describes the methods which are used in a | |
32 remote debugging scenario. It is only necessary because RMI | |
33 requires that all such methods throw RemoteException, which is a | |
34 checked (i.e., not a Runtime) exception. Since we already have a | |
35 suitable runtime exception (DebuggerException) present in the | |
36 signatures for all of the debugger-related methods, we would like | |
37 to repurpose this to wrap RemoteExceptions. This is done by | |
38 wrapping the actual remote debugger object | |
39 </P> | |
40 | |
41 <P> NOTE that this interface currently assumes that the debugger | |
42 on the remote machine has already been attached to the target | |
43 process or has opened the desired core file. This implies that the | |
44 machine hosting the user interface can not effect | |
45 attaching/detaching. Currently this restriction has been enforced | |
46 to make the user interface less confusing, but there will also be | |
47 security concerns with allowing clients to attach to arbitrary | |
48 remote processes. </P> | |
