*** Bug 736136 has been marked as a duplicate of this bug. ***

Comment 2 Lukas Krejci 2011-09-08 13:14:06 UTC

The exception is very strange. It might be caused by a failure to initialize or even find the augeas native libs or augeas binding library or the RHQ augeas plugin none of which should ever happen when initializing resources from the apache plugin.

Mike, could you please try and provide more detailed repro steps for this? Was this discovered on a Linux/Unix/Windows box? I'm especially interested in what plugins were deployed, what and how many apache instances were inventoried and if the agent installation wasn't tampered with.

I can't see how the provided repro steps would directly trigger this error. I think it was more of an accidental match.

Comment 3 Lukas Krejci 2011-09-08 13:15:21 UTC

Also I re-opened bug 736136 because it most definitely isn't a duplicate of this bug.
