Subject [jira] Commented: (HARMONY-3711) [drlvm][gc] kernel test RuntimeTest.test_freeMemory fails intermittently
Date Thu, 17 Jan 2008 14:01:40 GMT

    [ https://issues.apache.org/jira/browse/HARMONY-3711?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12559930#action_12559930

Xiao-Feng Li commented on HARMONY-3711:

Thanks, Alexey. 

freeMemory() is an approximation according to the API spec. The test case looks like to require
freeMemory() to reflect 2KB size change of free memory. That looks like too rigorous. Since
the spec doesn't give the minimal changed size requirement, it's hard to say what granularity
is most reasonable. In my personal opinion, something close to 1MB is not unacceptable. :-)
