Setting to high, for eng. to determine if it is still an issue
Comment 2 John Sanda 2011-09-28 11:26:28 EDT
I believe that this is a file permissions issue. The agent currently does not check whether or not the file is readable. Mike can you please confirm whether or not classpath.sh is readable by the agent?
Comment 3 Heiko W. Rupp 2011-09-28 12:06:43 EDT
Mike could you tell what you were trying to do when this showed up?

Were you trying to inventory scripts (script plugin)?
Comment 4 John Sanda 2011-09-28 15:11:56 EDT
When generating the initial change set, if a file is not readable, it is   skipped and excluded from the change set since we cannot compute the SHA for the file.
When generating a drift change set, if we detect a new file that is not readable, we skip it as well since we cannot compute the SHA. Now if an existing file that is already being monitored for drift has its permissions changed such that it is no longer readable, then it is treated and recorded as a deleted file entry.

Comment 5 Mike Foley 2011-09-29 14:19:36 EDT
tested with files with and without rw permission.  could not reproduce.
Comment 8 Stefan Negrea 2012-02-08 17:20:53 EST
The discovery process was not using the home directory for the JBoss instance as relative path for the file. Instead it was defaulting to the home directory of the agent installation. Since the file was not found among the agent files, it would throw an exception during SHA256 computation. 

I visually inspected the rest of this component and this was the only occurrence of the problem.

Closing as this was implemented in RHQ 4.3 and has not been reopened since.
