Major The test RpcManagerMBeanTest.testEnableJmxStats tries to write to the "StatisticsEnabled" attribute but fails. The operation doesn't throw an exception, but it does log this WARN message:
10:43:42,079 WARN (testng-RpcManagerMBeanTest:) [ResourceDMBean] ISPN000043: Exception while writing value for attribute statisticsEnabled java.lang.NullPointerException at org.infinispan.jmx.ResourceDMBean$InvokableSetterBasedMBeanAttributeInfo.invoke(ResourceDMBean.java:391) at org.infinispan.jmx.ResourceDMBean.setNamedAttribute(ResourceDMBean.java:325) at org.infinispan.jmx.ResourceDMBean.setAttribute(ResourceDMBean.java:212) at com.sun.jmx.interceptor.DefaultMBeanServerInterceptor.setAttribute(DefaultMBeanServerInterceptor.java:746) at com.sun.jmx.mbeanserver.JmxMBeanServer.setAttribute(JmxMBeanServer.java:729) at org.infinispan.jmx.RpcManagerMBeanTest.testEnableJmxStats(RpcManagerMBeanTest.java:134)
Because statistics are still enabled, the test then fails with an assertion error:
10:43:42,464 ERROR (testng-RpcManagerMBeanTest:) [UnitTestTestNGListener] Test testEnableJmxStats(org.infinispan.jmx.RpcManagerMBeanTest) failed. java.lang.AssertionError: expected [-1] but found [1] at org.testng.Assert.fail(Assert.java:94) at org.testng.Assert.failNotEquals(Assert.java:494) at org.testng.Assert.assertEquals(Assert.java:123) at org.testng.Assert.assertEquals(Assert.java:165) at org.infinispan.jmx.RpcManagerMBeanTest.testEnableJmxStats(RpcManagerMBeanTest.java:138)
