[ http://issues.apache.org/jira/browse/DERBY-1497?page=all ]
Andreas Korneliussen reopened DERBY-1497:
-----------------------------------------
Will update the fix so that a constructor of DisconnectException which takes
Throwable is used.
After applying the new fix, the stack trace for the exception contains the
following information when running the BlobOutOfMem repro in DERBY-550 on Java
6 (Mustang):
java.sql.SQLException: Attempt to fully materialize lob data that is too large
for the JVM. The connection has been terminated.
