Re: Help needed with concurrency bug

[Peter Firmstone]

Here's the context, including permissions, so yes RuntimePermission A 
passes in this case, this is the passing test, now all I have to do is 
figure out the domain that doesn't have RuntimePermission A in the 
failing test, that should narrow it down.

Somehow this context passed RuntimePermission A, but you can't see

I've modified AggregratePolicyProvider in skunk (see recent commit), 
after the mods I'm unable to get it to lock up after exiting the 
debugger.

The following is specific to:

com/sun/jini/test/impl/start/aggregatepolicyprovider/GetContextTest.td

I've just come across the concurrency issue (experienced randomly when
attempting to debug any of the failing tests) in the existing River 
trunk
code, after exiting the debugger, the test is in a deadlocked 
state, here's
the thread dump:

    

Two threads arriving at the same point doesn't imply deadlock, in fact
it can mean quite the opposite. Deadlock requires two threads taking
resources in opposite orders so T1 takes a and tries to take b, T2
takes b and tries to take a. Thus I wouldn't expect both threads to be
blocking in implies.

So both threads arrived at AggregatePolicyProvider.implies but note
that method is not synchronized and the stack does not include mention
of getCurrentSubPolicy which does take a lock.

Thing is, the debugger itself could be the culprit, especially given
what you do below in terms of attempting a print.

If at all possible, it's going to be better to leave the debugger out
and wait for the test to deadlock, after which using jstack will give
a full dump and include a note of locks taken as well (something it
looks like the debugger above, doesn't do).

 
In this case I've tried to print the domain (ProtectionDomain), as 
you can
see two threads have arrived at the same breakpoint.
