[jboss-jira] [JBoss JIRA] Commented: (JGRP-604) ENCRYPT: issues with keystore

[Vladimir Blagojevic (JIRA)]

    [ https://jira.jboss.org/jira/browse/JGRP-604?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12429908#action_12429908 ] 

Vladimir Blagojevic commented on JGRP-604:
------------------------------------------

The problem seems to be related to encoding of strings in the message payload. If we use RpcDispatcher then MethodCall object is serialized into payload and it contains string for method name. If we change RpcDispatcher.testLargeReturnValue() not to use dispatcher but to simply send messages then the test never fails.

> - 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"/>
