In the past 30 minutes of working in CFBuilder (I have it as an Eclipse Plug in), I got this error 4 times: A stack overflow has occurred. You are recommended to exit the workbench. Subsequent errors may happen and may terminate the workbench without warning. See the .log file for more details. Do you want to exit workbench?. together with: Unhandled event loop exception java.lang.StackOverflowError The log file had this: !ENTRY org.eclipse.ui 4 0 2010-05-11 09:41:51.951 !MESSAGE Unhandled event loop exception !STACK 0 java.lang.StackOverflowError at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.mergeSort(Unknown Source) at java.util.Arrays.sort(Unknown Source) at com.adobe.ide.cfml.parser.generated.CFMLParserBase.getVariableInfo(CFMLParserBase.java:1613) at com.adobe.ide.cfml.parser.generated.CFMLParserBase.getVariableInfo(CFMLParserBase.java:1603) at com.adobe.ide.editor.model.CFMLDOMUtils.getVariable(CFMLDOMUtils.java:2375) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromNode(CFMLDOMUtils.java:2484) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromFunctionCall(CFMLDOMUtils.java:2168) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromNode(CFMLDOMUtils.java:2495) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromFunctionCall(CFMLDOMUtils.java:2168) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromNode(CFMLDOMUtils.java:2495) at com.adobe.ide.editor.model.CFMLDOMUtils.getComponentNameFromFunctionCall(CFMLDOMUtils.java:2168) (and so on - repeat n times) It happens whenever I copy/paste something.
