This happens generally if something during the build changes a JAR file that is
currently open by the VM (e.g. a Maven plugin). If you compile a maven plugin
and then use it afterwards, you should split your maven build to do this in 2
separate maven invocations. This is a known bug to all JVMs: The native zlib
code reading the JAR files segfaults if a JAR file changes while opened by a
classloader.
Otherwise: Fix Maven or the plugin that opens the JAR file to call
URLClassLoader.close() if it detects Java 7. This can be done by doing
instanceof Closeable on your classloader and then close it using a cast:
If (classloader instanceof Closeable) {
((Closeable) classloader).close();
}
E.g. see this example: http://goo.gl/e5XHe
Of couse this would only work if you are using Java 7 to run Maven, the above
code will do nothing on Java 6 and the bugs stays.
