ant test-compiled consumes excessive memory (unless it hangs first)
-------------------------------------------------------------------
Key: JRUBY-1342
URL: http://jira.codehaus.org/browse/JRUBY-1342
Project: JRuby
Issue Type: Bug
Components: Miscellaneous
Environment: trunk, WinXp, Java 6
Reporter: Bill Dortch
Assignee: Thomas E Enebo
ant test-compiled consumes excessive memory, unless it hangs first. On my poor
old machine with only 500MB RAM, I have to unload everything else before
running it (a pain in its own right), and even then everything slows to a crawl
as usage get up over 900MB virtual. ant test-interpreted does not have this
problem.
However, test-compiled often hangs before it gets to that point. A println
placed in TestUnitTestSuite shows it stops (with CPU pegged) in
rubicon/test_exception:
