This bug was originally marked as duplicate of bug 242048, that is already resolved. This bug is still valid, so this seems to be another bug, but it might be related. Build: NetBeans IDE 8.1 (Build 201510222201) VM: Java HotSpot(TM) 64-Bit Server VM, 25.25-b02, Java(TM) SE Runtime Environment, 1.8.0_25-b17 OS: Mac OS X User Comments: GUEST: My app suddenly re-deployed (although I hadn't requested this at all), but then NetBeans behaved weirdly and finally froze, and I wanted to end it gracefully for a restart. It closed, but the netbeans64.exe process didn't terminate. I had to kill the Tomcat process too. NetBeans was still alive and started another Tomcat process. I also killed it. Then NetBeans closed. GUEST: No idea GUEST: Unsure GUEST: Wanted to clear output pane from the previous program run. GUEST: Mp idea why this happens Stacktrace: java.lang.OutOfMemoryError: Java heap space at java.util.Arrays.copyOf(Arrays.java:3332) at java.lang.String.<init>(String.java:166) at java.nio.DirectCharBufferRS.toString(DirectCharBufferRS.java:422) at java.nio.CharBuffer.toString(CharBuffer.java:1241) at org.netbeans.core.output2.AbstractLines.getText(AbstractLines.java:202) at org.netbeans.core.output2.OutputDocument.getText(OutputDocument.java:177)
