Verified that you get the expected error message in I20041216-2000. |
When compiling following class import java.util.ArrayList; import java.util.List; public class CompilerNullPointerTest { List someList = new ArrayList(); public ArrayList getSomeList() { return someList; } } I get the following NullPointerException with M3. When changing List someList = new ArrayList(); to List<Object> someList = new ArrayList<Object>(); I get the expected "Type mismatch: cannot convert from List<Object> to ArrayList" error message. !ENTRY org.eclipse.jdt.core 4 4 2004-12-17 10:37:51.31 !MESSAGE Exception occurred during problem detection: !STACK 0 java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding.needsUncheckedConversion(ReferenceBinding.java:660) at org.eclipse.jdt.internal.compiler.ast.ReturnStatement.resolve(ReturnStatement.java:222) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolveStatements(AbstractMethodDeclaration.java:400) at org.eclipse.jdt.internal.compiler.ast.MethodDeclaration.resolveStatements(MethodDeclaration.java:147) at org.eclipse.jdt.internal.compiler.ast.AbstractMethodDeclaration.resolve(AbstractMethodDeclaration.java:378) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:985) at org.eclipse.jdt.internal.compiler.ast.TypeDeclaration.resolve(TypeDeclaration.java:1034) at org.eclipse.jdt.internal.compiler.ast.CompilationUnitDeclaration.resolve(CompilationUnitDeclaration.java:280) at org.eclipse.jdt.internal.compiler.Compiler.resolve(Compiler.java:566) at org.eclipse.jdt.internal.core.CompilationUnitProblemFinder.process(CompilationUnitProblemFinder.java:175) at org.eclipse.jdt.internal.core.CompilationUnit.buildStructure(CompilationUnit.java:143) at org.eclipse.jdt.internal.core.Openable.generateInfos(Openable.java:203) at org.eclipse.jdt.internal.core.JavaElement.openWhenClosed(JavaElement.java:553) at org.eclipse.jdt.internal.core.CompilationUnit.makeConsistent(CompilationUnit.java:978) at org.eclipse.jdt.internal.core.ReconcileWorkingCopyOperation.executeOperation(ReconcileWorkingCopyOperation.java:60) 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:1104) 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:96) 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)
