Exception in org.apache.xindice.core.DocumentCache$CacheKey.equals

Hi,

This problem is driving me nuts at the moment. I'm building a web app
based on Xindice, but for some reason I often get (at seemingly no
predictable time) an exception with the following trace:

DEBUG>
java.lang.NullPointerException
        at
org.apache.xindice.core.DocumentCache$CacheKey.equals(DocumentCache.java:171)
        at java.util.WeakHashMap.eq(WeakHashMap.java:248)

        at

        at
org.openorb.net.ServerManagerImpl$PoolThread.run(ServerManagerImpl.java:1557)

I feel this has to be a bug in the server, but I have no idea what could
be causing it. Does anybody have any ideas? I have to get this solved
soon. 

ps: this is a resend, if nobody has any idea, could I at least get a
reply so I know somebody saw it?

thanks -mike

Are you using 1.0 or the latest CVS version? I believe I have seen this
problem before and I believe it was fixed after 1.0.
