Robert Scholte commented on MCOMPILER-360:
------------------------------------------
The fix seems quite simple
https://maven.apache.org/plugins/maven-compiler-plugin/xref/org/apache/maven/plugin/compiler/CompilerMojo.html#L243
{code}
Throwable cause = pathException.getValue();
{code}
This should be good enough. Do you know which dependency causes this issue? I'd
like to have an integration test just to verify the fix.
