[ https://issues.apache.org/jira/browse/HARMONY-2521?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12464445 ]
Mark Hindess commented on HARMONY-2521:
---------------------------------------
After applying the fix, I get some issues. There must be a timing issues since either the test crashes with;
[junit] Running javax.swing.plaf.basic.BasicTextUITest
*** glibc detected *** double free or corruption (out): 0x08348218 ***
[junit] Test javax.swing.plaf.basic.BasicTextUITest FAILED
or the test fails with:
testCallOrder Failure
expected:<...installUI::uninstall
[Defaults::uninstallKeyboardActions::uninstallListener]
s::> but was:<...installUI::uninstall
[Listeners::uninstallDefaults::uninstallKeyboardAction]
s::>
