Doesn't matter if the arrays component type is primitive or a reference type (including type variables). Added missing check for type parameter bounds. Added GenericTypeTest#test461. Fixed Verified in I20050214 |
This code is illegal because an array type cannot be a bound: class Foo<T extends int[]> { } However, this crashes the compiler: java.lang.ClassCastException: org.eclipse.jdt.internal.compiler.lookup.ArrayBinding at org.eclipse.jdt.internal.compiler.lookup.Scope.connectTypeVariables(Scope.java:274) at org.eclipse.jdt.internal.compiler.lookup.ClassScope.connectTypeHierarchy(ClassScope.java:861) at org.eclipse.jdt.internal.compiler.lookup.CompilationUnitScope.connectTypeHierarchy(CompilationUnitScope.java:243) at org.eclipse.jdt.internal.compiler.lookup.LookupEnvironment.completeTypeBindings(LookupEnvironment.java:195) at org.eclipse.jdt.internal.compiler.Compiler.beginToCompile(Compiler.java:307) at org.eclipse.jdt.internal.compiler.Compiler.resolve(Compiler.java:546) at org.eclipse.jdt.internal.compiler.Compiler.resolve(Compiler.java:610) at org.eclipse.jdt.internal.core.CompilationUnitProblemFinder.process(CompilationUnitProblemFinder.java:165) at org.eclipse.jdt.internal.core.CompilationUnitProblemFinder.process(CompilationUnitProblemFinder.java:213) at org.eclipse.jdt.internal.core.ReconcileWorkingCopyOperation.executeOperation(ReconcileWorkingCopyOperation.java:78) at org.eclipse.jdt.internal.core.JavaModelOperation.run(JavaModelOperation.java:700) at org.eclipse.jdt.internal.core.JavaModelOperation.runOperation(JavaModelOperation.java:739) at org.eclipse.jdt.internal.core.CompilationUnit.reconcile(CompilationUnit.java:1105) at org.eclipse.jdt.internal.ui.text.java.JavaReconcilingStrategy.reconcile(JavaReconcilingStrategy.java:91) at org.eclipse.jdt.internal.ui.text.java.JavaReconcilingStrategy.reconcile(JavaReconcilingStrategy.java:133) at org.eclipse.jdt.internal.ui.text.CompositeReconcilingStrategy.reconcile(CompositeReconcilingStrategy.java:86) at org.eclipse.jdt.internal.ui.text.JavaCompositeReconcilingStrategy.reconcile(JavaCompositeReconcilingStrategy.java:94) at org.eclipse.jface.text.reconciler.MonoReconciler.process(MonoReconciler.java:75) at org.eclipse.jdt.internal.ui.text.JavaReconciler.process(JavaReconciler.java:318) at org.eclipse.jface.text.reconciler.AbstractReconciler$BackgroundThread.run(AbstractReconciler.java:204)
