Caused by: java.lang.NullPointerException at
org.apache.maven.plugin.compiler.TestCompilerMojo.preparePaths
(TestCompilerMojo.java:254) at
org.apache.maven.plugin.compiler.AbstractCompilerMojo.execute
(AbstractCompilerMojo.java:792)

I assume line number does not exactly fit here. But as already guessed
Throwable cause may already be null. So this is just unsafe code that needs to
be fixed.
