["Robert Scholte (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MCOMPILER-360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16607066#comment-16607066 ] 

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.
