Errors in jdbc4.LobStreamTest if derbyclient.jar is first in the classpath

I see the following errors in jdbc4.LobStreamTest if derbyclient.jar is before derby.jar on trunk 10.11 Rev: 1533320

There were 2 errors:

I notice derbyclient.jar contains
Mon Oct 21 13:30:14 PDT 2013 org/apache/derby/iapi/error/ExceptionUtil$1.class
Mon Oct 21 13:30:14 PDT 2013 org/apache/derby/iapi/error/ExceptionUtil.class

which I think is only supposed to be in derby.jar
