[Bigdata-developers] IllegalMonitorStateException on close

[ryan <ry...@os...>]

Hi All,
I'm trying to add a feature to my project that will allow a user to disconnect 
from a locally-connected BigData (1.3.1) engine, start up the network server, 
and reconnect to the now-networked repository.

The problem is that every time I I try to close my local connection, I get an 
IllegalMonitorStateException that appears to be preventing the network server 
from working correctly.

The pertinent stack trace is: 
java.lang.IllegalMonitorStateException
	at 
java.util.concurrent.locks.ReentrantReadWriteLock$Sync.tryRelease(ReentrantReadWriteLock.java:374)
	at 
java.util.concurrent.locks.AbstractQueuedSynchronizer.release(AbstractQueuedSynchronizer.java:1260)
	at 
java.util.concurrent.locks.ReentrantReadWriteLock$WriteLock.unlock(ReentrantReadWriteLock.java:1131)
	at 
com.bigdata.rdf.sail.BigdataSail$BigdataSailConnection.close(BigdataSail.java:3349)
	at 
org.openrdf.repository.sail.SailRepositoryConnection.close(SailRepositoryConnection.java:109)


With the default OpenRDF backing store, the system will wait a little bit, and 
then close connections for you if you don't close them first. I've tried both 
ways (closing the connection first, then the repository, and just closing the 
repository) with no difference. 

I'm running on java 1.7, bigdata 1.3.1, on a linux host.

I'm at a loss for troubleshooting. I'd be grateful for any advice you might 
have.

Thanks,
ry
