ENCRYPT: issues with keystore
-----------------------------

                 Key: JGRP-604
                 URL: http://jira.jboss.com/jira/browse/JGRP-604
             Project: JGroups
          Issue Type: Bug
            Reporter: Bela Ban
         Assigned To: Bela Ban
             Fix For: 2.7
         Attachments: tmp2.xml

If we use ENCRYPT with a keystore and fragmentation, then ENCRYPT throws the following exception:

09:35:45,920 [WARN] [Incoming,demo,192.168.2.3:49952] ENCRYPT.up(): exception occurred decrypting message

To reproduce:
- Create a configuration with the following entries present:
  <ENCRYPT key_store_name="defaultStore.keystore"  store_password="changeit" alias="myKey"/>	
  <FRAG2 frag_size="60000"/>
- Run RpcDispatcherTest.testLargeReturnValue (the stack has to include ENCRYPT and FRAG2).

Note that this error does not occur with
<ENCRYPT encrypt_entire_message="false" sym_init="128" sym_algorithm="AES/ECB/PKCS5Padding" asym_init="512" asym_algorithm="RSA"/>
