Subject [jira] Updated: (HARMONY-3711) [drlvm][test] kernel test RuntimeTest.test_freeMemory fails intermittently
Date Fri, 18 Jan 2008 08:30:34 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-3711?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Alexey Varlamov updated HARMONY-3711:

    Summary: [drlvm][test] kernel test RuntimeTest.test_freeMemory fails intermittently  (was:
[drlvm][gc] kernel test RuntimeTest.test_freeMemory fails intermittently)

I've played a bit with the test and it appeared to be purely test issue:
Indeed with GCv4.1 test sometimes starts with nearly exhausted heap (> 1M free) and then
starts collection during the test cycle. But the test increments probe allocation geometrically
thus may not fit into intial limits.
