Hello,

I did a completely fresh setup of RHQ and Infinispan on our test-systems today and followed the instructions on the various documentation sites to monitor my systems.

For some reason the I was alerted a few minutes after I installed the infinispan module in the agent plugins that the DefaultCacheManager isn't available.

RHQ-Server

Version: 4.5.1, Build Number: c880f5a, java version "1.7.0_04"

Standard setup with Oracle and Infinispan RHQ Plugin 5.1.6.FINAL

RHQ-Agent

Version=RHQ 4.5.1, Build Number: c880f5a, java version "1.7.0_04"

Infinispan

Version: 5.1.6.FINAL, java version "1.7.0_04"

2 nodes with minimal configuration: distributed clustering, 1 named cache and jgroups tcp configuration, globalJmxStatistics enabled on global and named cache level

Any ideas how to fix that?
