Bug ID: 54513
Summary: NullPointerException in AprEndpoint$Poller.run
Product: Tomcat 8
Version: trunk
Hardware: PC
OS: Windows XP
Status: NEW
Severity: normal
Priority: P2
Component: Connectors
Assignee: dev@tomcat.apache.org
Reporter: knst.koli...@gmail.com
Classification: Unclassified
Trunk at r1441188, running the test suite with APR connector, Native 1.1.26
Windows 32-bit with JDK 7u11.
I encountered the following when running
org.apache.catalina.loader.TestVirtualContext test
On second re-run of the test the same issue happened, so it is as if there is
something specific here. I have not encountered the issue with the rest of
testsuite yet.

WARNING: Unexpected poller error
java.lang.NullPointerException
at
org.apache.tomcat.util.net.AprEndpoint$AprSocketWrapper.access$200(AprEndpoint.java:2198)
at org.apache.tomcat.util.net.AprEndpoint$Poller.run(AprEndpoint.java:1632)
at java.lang.Thread.run(Thread.java:722)
]]]
The code at AprEndpoint$Poller.run(AprEndpoint.java:1632) is
1628 for (int n = 0; n < rv; n++) {
1629 timeouts.remove(desc[n*2+1]);
1630 AprSocketWrapper wrapper = connections.get(
1631 Long.valueOf(desc[n*2+1]));
1632 wrapper.pollerFlags = wrapper.pollerFlags & ~((int) desc[n*2]);
I suspect that "wrapper" is null here.
The above code is specific to Tomcat trunk and is not present in 7.0.x.
When this happened, the test hung for 15 minutes (1000 secs) waiting on a
socket read. When time out passed, it continued to run all the other tests.
