Tomohito Nakayama commented on DERBY-1513:
------------------------------------------
With DERBY-1513_2.patch, MemorySavedByteArrayOutputStream did not work as
before.
Using jdb, I found size of buf and count is not same value when toByteArray
method was called.
Exception occurred: java.lang.OutOfMemoryError (uncaught)
