Kathey Marsden updated DERBY-5347:
----------------------------------
Attachment: derby-5347_diff.txt
Attaching a patch for this issue. I am not ready commit but would appreciate
review. I don' think this will make it for the release as I would like to
first understand some behavior I am seeing in manual testing of the case where
a client does not have permission to connect under security manager.
Without the patch, after a couple failed security attempts I am seeing the
server crash, but I am also seeing the same behavior without the patch. Either
I am seeing some previously existing serious bug or perhaps my permissions are
just way too restrictive in my policy file. I'll nail down what's going on and
file another bug if necessary.
