With 3.3.2 RC2 codebase: Noticed the following entry in the .log while running all JDTCore tests: !ENTRY org.eclipse.jdt.core 4 4 2008-01-29 12:47:21.296 !MESSAGE Could not retrieve declared fields !STACK 0 java.lang.NullPointerException at org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding.resolveTypeFor(SourceTypeBinding.java:1250) at org.eclipse.jdt.internal.compiler.lookup.SourceTypeBinding.fields(SourceTypeBinding.java:604) at org.eclipse.jdt.internal.compiler.lookup.ReferenceBinding.availableFields(ReferenceBinding.java:167) at org.eclipse.jdt.core.dom.TypeBinding.getDeclaredFields(TypeBinding.java:237) at org.eclipse.jdt.core.tests.dom.BatchASTCreationTests.test070(BatchASTCreationTests.java:1624) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at junit.framework.TestCase.runTest(TestCase.java:164) at junit.framework.TestCase.runBare(TestCase.java:130) at junit.framework.TestResult$1.protect(TestResult.java:106) at junit.framework.TestResult.runProtected(TestResult.java:124) at junit.framework.TestResult.run(TestResult.java:109) at junit.framework.TestCase.run(TestCase.java:120) at junit.framework.TestSuite.runTest(TestSuite.java:230) at org.eclipse.jdt.core.tests.model.SuiteOfTestCases$Suite.runTest(SuiteOfTestCases.java:99) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.core.tests.model.SuiteOfTestCases$Suite.superRun(SuiteOfTestCases.java:83) at org.eclipse.jdt.core.tests.model.SuiteOfTestCases$1.protect(SuiteOfTestCases.java:71) at junit.framework.TestResult.runProtected(TestResult.java:124) at org.eclipse.jdt.core.tests.model.SuiteOfTestCases$Suite.run(SuiteOfTestCases.java:80) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at junit.framework.TestSuite.runTest(TestSuite.java:230) at junit.framework.TestSuite.run(TestSuite.java:225) at org.eclipse.jdt.internal.junit.runner.junit3.JUnit3TestReference.run(JUnit3TestReference.java:130) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:460) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:673) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:386) at org.eclipse.pde.internal.junit.runtime.RemotePluginTestRunner.main(RemotePluginTestRunner.java:58) at org.eclipse.pde.internal.junit.runtime.CoreTestApplication.run(CoreTestApplication.java:24) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.internal.app.EclipseAppContainer.callMethod(EclipseAppContainer.java:572) at org.eclipse.equinox.internal.app.EclipseAppHandle.run(EclipseAppHandle.java:171) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.runApplication(EclipseAppLauncher.java:106) at org.eclipse.core.runtime.internal.adaptor.EclipseAppLauncher.start(EclipseAppLauncher.java:76) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:363) at org.eclipse.core.runtime.adaptor.EclipseStarter.run(EclipseStarter.java:176) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at org.eclipse.equinox.launcher.Main.invokeFramework(Main.java:508) at org.eclipse.equinox.launcher.Main.basicRun(Main.java:447) at org.eclipse.equinox.launcher.Main.run(Main.java:1173) at org.eclipse.equinox.launcher.Main.main(Main.java:1148)
The test did not fail, but the NPE seems like a case where we cannot lazily resolve fields.
I could not reproduce.
Closing as WORKSFORME. Please reopen if you get it again.
Verified for 3.5M1 using I20080805-1307
While running org.eclipse.jdt.core.tests.dom.RunAllTests in the IDE I see this exact NPE (using HEAD as of 3.7.0 RC4). The NPE isn't surprising but the way it is caught and logged might deserve a second and third thought: The NPE is caught in dom's TypeBinding.getDeclaredFields(): } catch (RuntimeException e) { /* in case a method cannot be resolvable due to missing jars on the classpath * see https://bugs.eclipse.org/bugs/show_bug.cgi?id=57871 * https://bugs.eclipse.org/bugs/show_bug.cgi?id=63550 * https://bugs.eclipse.org/bugs/show_bug.cgi?id=64299 */ org.eclipse.jdt.internal.core.util.Util.log(e, "Could not retrieve declared fields"); //$NON-NLS-1$ } return this.fields = NO_VARIABLE_BINDINGS; The latter two of the mentioned bugs have the explanation: trying to resolve fields after scope has been discarded. Is it wrong usage to call getDeclaredFields() after the compiler may have discarded scopes (how can the client tell?)? If it is expected behavior (and returning NO_VARIABLE_BINDINGS is the expected outcome), why is the exception logged? Feel free to re-close but the behavior felt strange to me and seeing this report as cannot reproduce didn't look too satisfactory, either :)
Closing again. If this needs to be improved, it should be done in a separate bug report.
Verified.
