Currently, jtreg prints following message when any of action fails in agentvm mode.
"result: Error. Agent error: java.lang.Exception: Agent 3 timed out with a timeout of 1200 seconds; check console log for any additional details "

This message is very confusing. It mentions "Agent error." so people might think about some Agen/Jtreg communication issues.
It would be better to describe the operation which timed out. At least to clearly set that it is not jtreg/agent problem but a timeout caused by issues with agentvm actions (run/compile).
