[jira] (SUREFIRE-864) NPE when unit test loads resources from JAR

    [ https://jira.codehaus.org/browse/SUREFIRE-864?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=312340#comment-312340 ] 

Kristian Rosenvold commented on SUREFIRE-864:
---------------------------------------------

The sample project seems to be missing the source for TestSurefireLib, any chance you have that ?

(Sorry about the delay...)

> 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.
