-------------------------------------
Summary: NPE when unit test loads resources from JAR
Key: SUREFIRE-864
URL: https://jira.codehaus.org/browse/SUREFIRE-864
Project: Maven Surefire
Issue Type: Bug
Affects Versions: 2.12, 2.11, 2.10, 2.9
Environment: Windows 64-bit, Eclipse Maven plug-in
Reporter: Luke Stevens
Attachments: TestSurefire.zip
I have a unit test that reads resources from a JAR built by another project.
This works totally fine when running JUnit within Eclipse. But when building
under Maven, it hits an error:
java.lang.NullPointerException
at java.io.FilterInputStream.close(FilterInputStream.java:155)
at
sun.net.www.protocol.jar.JarURLConnection$JarURLInputStream.close(JarURLConnection.java:90)
...
Suppressing this error (which occurs on close, after all) only leads to others.
Some digging reveals that this is probably related to a longstanding
classloader bug in the JVM:

A very simple project is attached to demonstrate the problem.
