This remedies test failures observed with JavaALSSuite with IBM and Oracle Java owing to a lower default size in comparison to the size with OpenJDK. 4096k is a suitable default where the tests pass with each Java vendor tested. The alternative is to reduce the number of iterations in the test (no observed failures with 5 iterations instead of 15).\r\n\r\n-Xss works with Oracle's HotSpot VM, IBM's J9 VM and OpenJDK (IcedTea).\r\n\r\nI have ensured this does not have any negative implications for other tests."},"comment":{"url":"https://api.github.com/repos/apache/spark/issues/comments/110467865","html_url":"https://github.com/apache/spark/pull/6727#issuecomment-110467865","issue_url":"https://api.github.com/repos/apache/spark/issues/6727","id":110467865,"user":{"login":"squito","id":71240,"avatar_url":"https://avatars.githubusercontent.com/u/71240?v=3","gravatar_id":"","url":"https://api.github.com/users/squito","html_url":"https://github.com/squito","followers_url":"https://api.github.com/users/squito/followers","following_url":"https://api.github.com/users/squito/following{/other_user}","gists_url":"https://api.github.com/users/squito/gists{/gist_id}","starred_url":"https://api.github.com/users/squito/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/squito/subscriptions","organizations_url":"https://api.github.com/users/squito/orgs","repos_url":"https://api.github.com/users/squito/repos","events_url":"https://api.github.com/users/squito/events{/privacy}","received_events_url":"https://api.github.com/users/squito/received_events","type":"User","site_admin":false},"created_at":"2015-06-09T19:12:59Z","updated_at":"2015-06-09T19:12:59Z","body":"I'd say you should just add the changes to the sbt build here as well"}}
