Also, FWIW this occured in a JavaScript file that was external source so the wrapping project is not a JS project so might not have any useful environment properties set. With that said when debugging this is a fairly common case since the script URI are frequently http based. Can you provide me step-by-step instructions to reproduce? |
With the following script: var foo = []; foo.push("x"); foo.push("y"); When I try and set a breakpoint on the line with foo.push("x") I get the following stack showing up in the -debug console. I'm running off of HEAD. java.lang.NullPointerException at org.eclipse.wst.jsdt.internal.compiler.lookup.ArrayBinding.getExactMethod(ArrayBinding.java:233) at org.eclipse.wst.jsdt.internal.compiler.lookup.Scope.findExactMethod(Scope.java:401) at org.eclipse.wst.jsdt.internal.compiler.lookup.Scope.getMethod(Scope.java:1813) at org.eclipse.wst.jsdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:307) 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.core.dom.JavaScriptUnitResolver.resolve(JavaScriptUnitResolver.java:859) at org.eclipse.wst.jsdt.core.dom.JavaScriptUnitResolver.resolve(JavaScriptUnitResolver.java:527) at org.eclipse.wst.jsdt.core.dom.ASTParser.internalCreateAST(ASTParser.java:862) at org.eclipse.wst.jsdt.core.dom.ASTParser.createAST(ASTParser.java:647) at org.eclipse.wst.jsdt.internal.ui.javaeditor.ASTProvider$1.run(ASTProvider.java:581) at org.eclipse.core.runtime.SafeRunner.run(SafeRunner.java:42) at org.eclipse.wst.jsdt.internal.ui.javaeditor.ASTProvider.createAST(ASTProvider.java:574) at org.eclipse.wst.jsdt.internal.ui.javaeditor.ASTProvider.getAST(ASTProvider.java:509) at org.eclipse.wst.jsdt.internal.ui.viewsupport.SelectionListenerWithASTManager$PartListenerGroup.calculateASTandInform(SelectionListenerWithASTManager.java:150) at org.eclipse.wst.jsdt.internal.ui.viewsupport.SelectionListenerWithASTManager$3.run(SelectionListenerWithASTManager.java:135) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:54)
