Rob Stryker commented on JBIDE-15574:
-------------------------------------

I did make a commit to update the the server jars to beta1, as that was needed for integrations testing anyway (always stay on the top of the stream), but in reality, there are still issues when using a java 6 jre to run eclipse and communicate with a wildfly server.  It appears the the NIO libraries have a requirement on API introduced in java7, specifically a class named  ReflectiveOperationException. 

I think now it becomes basically a requirement to run eclipse with java7 if you expect to be communicating with wildfly unless we can get the nio stuff fixed.

> This should be fixed in wildfly beta. There is nothing that tools can do to fix this. The relevant server jars need to rebuilt with a lower class version.

> We will switch our unit tests to beta1 as soon as it is available.
