[jboss-jira] [JBoss JIRA] (JGRP-2088) ArrayIndexOutOfBoundsException on ClassConfigurator.get()

[Manuel Dominguez Sarmiento (JIRA)]

Manuel Dominguez Sarmiento commented on JGRP-2088:
--------------------------------------------------

Thanks Bela, it now works by removing ENCRYPT and replacing with SYM_ENCRYPT below NAKACK2. This should probably be documented more clearly for other upgrading from previous versions. ENCRYPT should either be removed or deprecated, or at least log some kind of warning.

> Stepping through the code with the debugger shows that the following line is failing at ClassConfigurator.get() with magic = -1 thus the java.lang.ArrayIndexOutOfBoundsException
> return magic < 1024 ? magicMap[magic] : (Class)magicMapUser.get(Short.valueOf(magic));
> See attached jgroups.xml for configuration. This showed up when upgrading to 3.6.10 from 3.6.8 which worked fine.
