At various times when I have JavaScript files open, Eclipse starts to slow down, then eventually crashes. When it's slowing down, this is always the first thing that shows up in jstack: "Text Viewer Hover Presenter" daemon prio=1 tid=117a4c000 nid=0x120db2000 runnable [120db0000] java.lang.Thread.State: RUNNABLE at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.resetStacks(Parser.java:6887) at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.resumeAfterRecovery(Parser.java:6925) at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.resumeOnSyntaxError(Parser.java:6968) at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.parse(Parser.java:5719) at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.parse(Parser.java:6036) at org.eclipse.wst.jsdt.internal.compiler.parser.Parser.parse(Parser.java:5988) at org.eclipse.wst.jsdt.internal.codeassist.SelectionEngine.doParse(SelectionEngine.java:1286) at org.eclipse.wst.jsdt.internal.codeassist.impl.Engine.accept(Engine.java:91) at org.eclipse.wst.jsdt.internal.compiler.lookup.LookupEnvironment.askForBinding(LookupEnvironment.java:279) at org.eclipse.wst.jsdt.internal.compiler.lookup.PackageBinding.getTypeOrPackage(PackageBinding.java:249) at org.eclipse.wst.jsdt.internal.compiler.lookup.Scope.getTypeOrPackage(Scope.java:2105) at org.eclipse.wst.jsdt.internal.compiler.lookup.Scope.getBinding(Scope.java:1088) at org.eclipse.wst.jsdt.internal.compiler.ast.SingleNameReference.findBinding(SingleNameReference.java:478) at org.eclipse.wst.jsdt.internal.compiler.ast.FieldReference.resolveType(FieldReference.java:340) at org.eclipse.wst.jsdt.internal.compiler.ast.FieldReference.resolveType(FieldReference.java:275) at org.eclipse.wst.jsdt.internal.compiler.ast.BinaryExpression.resolveType(BinaryExpression.java:263) at org.eclipse.wst.jsdt.internal.compiler.ast.Expression.resolveTypeExpecting(Expression.java:540) at org.eclipse.wst.jsdt.internal.compiler.ast.IfStatement.resolve(IfStatement.java:189) at org.eclipse.wst.jsdt.internal.compiler.ast.IfStatement.resolve(IfStatement.java:193) at org.eclipse.wst.jsdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:350) at org.eclipse.wst.jsdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:137) at org.eclipse.wst.jsdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:304) at org.eclipse.wst.jsdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:375) at org.eclipse.wst.jsdt.internal.compiler.ast.FunctionExpression.resolveType(FunctionExpression.java:58) at org.eclipse.wst.jsdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:267) at org.eclipse.wst.jsdt.internal.compiler.ast.Expression.resolve(Expression.java:477) at org.eclipse.wst.jsdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:394) at org.eclipse.wst.jsdt.internal.codeassist.SelectionEngine.select(SelectionEngine.java:741) at org.eclipse.wst.jsdt.internal.core.Openable.codeSelect(Openable.java:167) at org.eclipse.wst.jsdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:318) at org.eclipse.wst.jsdt.internal.core.CompilationUnit.codeSelect(CompilationUnit.java:312) at org.eclipse.wst.jsdt.internal.ui.text.java.hover.AbstractJavaEditorTextHover.getHoverInfo(AbstractJavaEditorTextHover.java:114) at org.eclipse.wst.jsdt.internal.ui.text.java.hover.AbstractJavaEditorTextHover.getHoverInfo2(AbstractJavaEditorTextHover.java:95) at org.eclipse.wst.jsdt.internal.ui.text.java.hover.BestMatchHover.getHoverInfo2(BestMatchHover.java:147) at org.eclipse.wst.jsdt.internal.ui.text.java.hover.JavaEditorTextHoverProxy.getHoverInfo2(JavaEditorTextHoverProxy.java:78) at org.eclipse.jface.text.TextViewerHoverManager$4.run(TextViewerHoverManager.java:166)

Is that the only stack shown?

Here are two complete jstack calls. These occurred after I had opened a 24K JavaScript file, and Eclipse stopped responding. In this case it didn't end up crashing; it went back to normal after about 30 seconds.
Lowering severity since it's not a crash or indefinite hang. Sounds like a very slow operation instead.
OK, but see the original report...Eclipse does eventually crash (at least some of the time).
Created attachment 238128 [details] jstack output 3 I've got the stack trace almost the same as the second one. But I see no Parser/AST calculation/Validator etc. here (See jstack23882.log). The only SWTs Display.sleep(). The hang was caught while trying to see quickfixes menu by mouse clicking on a left ruller's marker.
Sorry, please read "jstack23882.log" as "jstack output 3 attachment".
Forgot to mention that environment for "jstack output 3" is Kepler 4.3.1 + WTP 3.5.1.
