Created attachment 27968 [details] TEST-org.apache.catalina.tribes.group.interceptors.TestOrderInterceptor.BIO.txt Running tests for 7.0.23 release candidate I noted that there was a NullPointerException in one of tribes tests: TEST-org.apache.catalina.tribes.group.interceptors.TestOrderInterceptor.BIO.txt 18.11.2011 9:27:56 org.apache.catalina.tribes.transport.nio.NioReceiver listen SEVERE: Unable to process request in NioReceiver java.lang.NullPointerException at org.apache.catalina.tribes.transport.nio.NioReceiver.listen(NioReceiver.java:274) at org.apache.catalina.tribes.transport.nio.NioReceiver.run(NioReceiver.java:414) at java.lang.Thread.run(Thread.java:662) ------------- ---------------- --------------- The test case did not fail, so it likely occurred during tearDown. The line in source code is 268 while (doListen() && selector != null) { (..) 272 events(); 273 socketTimeouts(); 274 int n = selector.select(getSelectorTimeout()); It is likely that selector field referenced on line 274 became null because of NioReceiver#stopListening() call. This issue was not observed on reruns. I am attaching complete log file from this test.
This has been fixed in trunk and 7.0.x and will be included in 7.0.24 onwards.
