I am looking at a ClassCastException for which I have no derby.log and
very little information (just a stack trace). The version is 10.2.2.0 -
(485682). The stack trace is:
Initial Exception; SQLState: 'XJ001' errorCode: '0' Msg: 'Java
exception: '[[Lorg.apache.derby.iapi.store.access.Qualifier; incomp
java.lang.ClassCastException:

It seems even the message is truncated somewhat. I looked at the
failing method and the exception seems to occur at one of two
invocations of:
(DataValueDescriptor) (orderableGetter.invoke(activation));
Unfortunately, this is my first time working with this particular code.
Has anyone seen this before or have any immediate ideas where to look
for a problem.
Thanks
Kathey
