By checking the related problem reports I found [1] which mentions org.eclipse.epp.package.java.product 4.5.0.I20150603-2000. I assume this happens on final mars as well then. [1] https://dev.eclipse.org/recommenders/committers/confess/#/incidents/559d181be4b0cf2e4bf548ee

The stack trace in the other report reads: java.lang.NullPointerException: at org.eclipse.jdt.internal.compiler.lookup.Scope.getConstructor0(Scope.java:2344) at org.eclipse.jdt.internal.compiler.lookup.Scope.getConstructor(Scope.java:2325) at org.eclipse.jdt.internal.compiler.ast.Statement.findConstructorBinding(Statement.java:430) at org.eclipse.jdt.internal.compiler.ast.QualifiedAllocationExpression.resolveTypeForQualifiedAllocationExpression(QualifiedAllocationExpression.java:561) at org.eclipse.jdt.internal.compiler.ast.QualifiedAllocationExpression.resolveType(QualifiedAllocationExpression.java:286) at org.eclipse.jdt.internal.compiler.ast.MessageSend.resolveType(MessageSend.java:662) at org.eclipse.jdt.internal.compiler.ast.Expression.resolve(Expression.java:1020) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:641) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:309) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:551) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1188) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1301) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:590) at org.eclipse.jdt.internal.codeassist.SelectionEngine.select(SelectionEngine.java:985) at org.eclipse.jdt.internal.core.Openable.codeSelect(Openable.java:163) This points towards QualifiedAllocationExpression:561 passing a null receiverType.
We finally have a repro for a similar stack trace: bug 494204 comment 1 *** This bug has been marked as a duplicate of bug 494204 ***
