Hello,

some of our unit tests (using PowerMock and xmlunit) fail with 8u161 (and u162) but work with 8u152. I cant reproduce the fault in a stand-alone program so it seems to be related to classloader/reflection magic of those tools, sorry. Is this a regression of 8159240 <http://bugs.java.com/viewbug.do?bugid=JDK-8159240> (not public?) Fixes in the CPU releases are kept private - hence the above bug is not public. The changesets do become public once the release is made public though. See : http://hg.openjdk.java.net/jdk8u/jdk8u/jaxws/rev/06086cb6c349

I don't think it's a factor for what you're seeing.

Classes nearer to those below were touched via JDK-8186080: Transform XML interfaces http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/cb84156d54b2 http://hg.openjdk.java.net/jdk8u/jdk8u/jaxp/rev/08a44c164993

This may be connected with some tools trying to redefine the classes perhaps. Needs more investigating. Perhaps the XMLSchemaLoader changes are a factor ?

Here is the stacktrace anyway: com.sun.org.apache.xerces.internal.impl.dv.DVFactoryException: Schema factory class com.sun.org.apache.xerces.internal.impl.dv.xs.SchemaDVFactoryImpl does not extend from SchemaDVFactory. at com.sun.org.apache.xerces.internal.impl.dv.SchemaDVFactory.getInstance(SchemaDVFactory.java:75) at com.sun.org.apache.xerces.internal.impl.dv.SchemaDVFactory.getInstance(SchemaDVFactory.java:57) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.reset(XMLSchemaLoader.java:1024) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadGrammar(XMLSchemaLoader.java:556) at com.sun.org.apache.xerces.internal.impl.xs.XMLSchemaLoader.loadGrammar(XMLSchemaLoader.java:535) at com.sun.org.apache.xerces.internal.jaxp.validation.XMLSchemaFactory.newSchema(XMLSchemaFactory.java:254) at javax.xml.validation.SchemaFactory.newSchema(SchemaFactory.java:638) at javax.xml.validation.SchemaFactory.newSchema(SchemaFactory.java:654) at com.seeburger.api.test.helpers.BuilderTestHelper.getCRSchemaValidator(BuilderTestHelper.java:57) at com.seeburger.api.test.helpers.BuilderTestHelper.validateAndCompare(BuilderTestHelper.java:73) at com.seeburger.api.test.KSMBuilderTest.testDeletePGP(KSMBuilderTest.java:196) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.junit.internal.runners.TestMethod.invoke(TestMethod.java:68) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl$PowerMockJUnit44MethodRunner.runTestMethod(PowerMockJUnit44RunnerDelegateImpl.java:310) at org.junit.internal.runners.MethodRoadie$2.run(MethodRoadie.java:89) at org.junit.internal.runners.MethodRoadie.runBeforesThenTestThenAfters(MethodRoadie.java:97) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl$PowerMockJUnit44MethodRunner.executeTest(PowerMockJUnit44RunnerDelegateImpl.java:294) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit47RunnerDelegateImpl$PowerMockJUnit47MethodRunner.executeTestInSuper(PowerMockJUnit47RunnerDelegateImpl.java:127) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit47RunnerDelegateImpl$PowerMockJUnit47MethodRunner.executeTest(PowerMockJUnit47RunnerDelegateImpl.java:82) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl$PowerMockJUnit44MethodRunner.runBeforesThenTestThenAfters(PowerMockJUnit44RunnerDelegateImpl.java:282) at org.junit.internal.runners.MethodRoadie.runTest(MethodRoadie.java:87) at org.junit.internal.runners.MethodRoadie.run(MethodRoadie.java:50) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl.invokeTestMethod(PowerMockJUnit44RunnerDelegateImpl.java:207) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl.runMethods(PowerMockJUnit44RunnerDelegateImpl.java:146) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl$1.run(PowerMockJUnit44RunnerDelegateImpl.java:120) at org.junit.internal.runners.ClassRoadie.runUnprotected(ClassRoadie.java:34) at org.junit.internal.runners.ClassRoadie.runProtected(ClassRoadie.java:44) at org.powermock.modules.junit4.internal.impl.PowerMockJUnit44RunnerDelegateImpl.run(PowerMockJUnit44RunnerDelegateImpl.java:122) at org.powermock.modules.junit4.common.internal.impl.JUnit4TestSuiteChunkerImpl.run(JUnit4TestSuiteChunkerImpl.java:106) at org.powermock.modules.junit4.common.internal.impl.AbstractCommonPowerMockRunner.run(AbstractCommonPowerMockRunner.java:53) at org.powermock.modules.junit4.PowerMockRunner.run(PowerMockRunner.java:59) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:86) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:539) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:761) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:461) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:207) on the classpath jaxb-impl-2.2.5.jar but the specific packages are only loaded from rt.jar and redefined.
