Random NPE while serializing bean sent --------------------------------------- Key: WELD-908 URL: https://issues.jboss.org/browse/WELD-908 Project: Weld Issue Type: Bug Affects Versions: 1.1.0.Final Environment: Glassfish 3.1 Reporter: Yannick Menager The problem happens randomly (like 50% of the time), when calling an EJB through it's remote interface, and passing a Session scoped object as an argument, resulting in an NPE: java.lang.NullPointerException at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1088) at java.io.ObjectOutputStream.writeUnshared(ObjectOutputStream.java:397) at org.jboss.weld.bean.proxy.util.SerializableProxy.writeObject(SerializableProxy.java:92) at sun.reflect.GeneratedMethodAccessor125.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at com.sun.corba.ee.impl.io.IIOPOutputStream.invokeObjectWriter(IIOPOutputStream.java:646) at com.sun.corba.ee.impl.io.IIOPOutputStream.outputObject(IIOPOutputStream.java:612) at com.sun.corba.ee.impl.io.IIOPOutputStream.simpleWriteObject(IIOPOutputStream.java:196) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValueInternal(ValueHandlerImpl.java:235) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValueWithVersion(ValueHandlerImpl.java:216) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValue(ValueHandlerImpl.java:180) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.callWriteValue(CDROutputStream_1_0.java:852) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.writeRMIIIOPValueType(CDROutputStream_1_0.java:837) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.write_value(CDROutputStream_1_0.java:962) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.write_value(CDROutputStream_1_0.java:976) at com.sun.corba.ee.impl.encoding.CDROutputObject.write_value(CDROutputObject.java:521) at com.sun.corba.ee.impl.corba.TCUtility.marshalIn(TCUtility.java:157) at com.sun.corba.ee.impl.corba.AnyImpl.write_value(AnyImpl.java:627) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.write_any(CDROutputStream_1_0.java:627) at com.sun.corba.ee.impl.encoding.CDROutputObject.write_any(CDROutputObject.java:489) at com.sun.corba.ee.impl.javax.rmi.CORBA.Util.writeAny(Util.java:366) at com.sun.corba.ee.impl.io.ValueHandlerImpl.write_Array(ValueHandlerImpl.java:499) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValueInternal(ValueHandlerImpl.java:233) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValueWithVersion(ValueHandlerImpl.java:216) at com.sun.corba.ee.impl.io.ValueHandlerImpl.writeValue(ValueHandlerImpl.java:180) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.callWriteValue(CDROutputStream_1_0.java:852) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.writeArray(CDROutputStream_1_0.java:768) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.write_value(CDROutputStream_1_0.java:949) at com.sun.corba.ee.impl.encoding.CDROutputStream_1_0.write_value(CDROutputStream_1_0.java:976) at com.sun.corba.ee.impl.encoding.CDROutputObject.write_value(CDROutputObject.java:521) at com.sun.corba.ee.impl.copyobject.ORBStreamObjectCopierImpl.copy(ORBStreamObjectCopierImpl.java:76) at com.sun.corba.ee.impl.copyobject.ORBStreamObjectCopierImpl.copy(ORBStreamObjectCopierImpl.java:65) at com.sun.corba.ee.impl.orbutil.copyobject.FallbackObjectCopierImpl.copy(FallbackObjectCopierImpl.java:69) at com.sun.corba.ee.impl.orbutil.copyobject.FallbackObjectCopierImpl.copy(FallbackObjectCopierImpl.java:59) at com.sun.corba.ee.impl.javax.rmi.CORBA.Util.copyObject(Util.java:771) at com.sun.corba.ee.impl.javax.rmi.CORBA.Util.copyObjects(Util.java:742) at com.sun.corba.ee.impl.presentation.rmi.DynamicMethodMarshallerImpl.copyArguments(DynamicMethodMarshallerImpl.java:439) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.privateInvoke(StubInvocationHandlerImpl.java:227) at com.sun.corba.ee.impl.presentation.rmi.StubInvocationHandlerImpl.invoke(StubInvocationHandlerImpl.java:152) ------------------------------------------ import java.io.Serializable; public class TestObj implements Serializable{ private String val; public TestObj() { } public TestObj(String val) { this.val = val; } public String getVal() { return val; } public void setVal(String val) { this.val = val; } } ------------------------------------------ @RequestScoped @Named("test") public class TestWeb { @EJB private RemoteService remoteService; @Inject private TestObj testObj; @Produces @SessionScoped public TestObj create() { return new TestObj("ads"); } public String getVal() { return remoteService.test(testObj); } }
