Getting java.lang.ArrayIndexOutOfBoundsException in executeUpdate()

[markaddleman]

We're getting

java.lang.ArrayIndexOutOfBoundsException: Array index out of range: 0

        at org.teiid.jdbc.PreparedStatementImpl.executeUpdate(PreparedStatementImpl.java:218)

very intermittently.  We don't have a test case yet but from a quick reading on the code, I think updateCounts[] should be marked as volatile.  We're making that change locally and testing that out but I thought I'd post it here for some feedback/guidance.

I should also mention that we're running in a highly patched 8.1 release.  A quick look at FishEye shows that no relevant source is different.  If you think it's worth retesting in 8.3, we will but it will be a while before we can.

If it is the stock JDBC translator, then https://issues.jboss.org/browse/TEIID-2401 would address that.

Thanks.  As it turns out, simply applying volatile didn't work.  We'll try the patch.  Thanks!
