Comment 1 Rafael Chaves

The deadlock seems to be between a call to MessageDigest.getInstance() and
instantiating a SecureRandom, and they do not seem to involve Eclipse class
loaders. It seems this comes from the Java class library instead. Nick, how
often have you seen this? Only once?

Here are the suspicious threads:

Comment 2 Nick Edgar

2005-02-10 21:34:32 EST

I only saw it once, immediately after switching to the new build.

Comment 3 Nick Edgar

2005-02-10 21:57:03 EST

Note that the "Framework Event Dispatcher" thread is blocked while holding the
workspace lock, and "Worker-6" (the auto-build job) is visiting the tree. 
Shouldn't the visitor also acquire the lock?
It looks like "Worker-5" is also blocked on the workspace lock.

Comment 4 Rafael Chaves

2005-02-11 16:34:53 EST

Actually, it seems "Framework Event Dispatcher" is being held due to scheduling
rule conflicts, it has not acquired the workspace lock yet. "Worker-6" (one of
the two threads involved in the deadlock) is the one owning the workspace lock.

"Worker-6" also owns the monitor for the Security class and then tries to load a
class using the system class loader (which requires the class loader lock).

"Worker-4" is loading a class using the system class loader (so it owns the
system class loader monitor), and then trying to acquire the monitor for the
Security class.

I believe that other than reporting this to the VM vendor, there is not much we
can do. Maybe ensure we initialize the SecureRandom used in the UUID
implementation during the workspace startup?

Comment 5 John Arthorne

2005-02-11 16:39:22 EST

I agree with Rafael's diagnosis.  I will do a search in the VM vendor's database
to see if it's a known problem.
