Comment 2 Tomas Hurka 2014-01-27 16:21:18 UTC 
There is 1,600,000 instances of org.netbeans.modules.gsf.testrunner.api.OutputLine. Most of them are hold by org.netbeans.modules.junit.output.JUnitTestcase#3. Its output instance variable contains ArrayList instance with 1,500,000 instances of OutputLine. Reassiging to java/junit for further evaluation.

As the OutputLines objects are stored in order to display a tooltip in the TRW suite/method nodes there is no reason to hold so much data, as at most TestsuiteNode.MAX_TOOLTIP_LINES lines will be displayed in the tooltip. In any case the output is visible both in output window and in the TRW's output pane. Thank you for reporting
