Maven hangs while using hsqldb and eclipselink

Hello,

 

My pom includes the dependencies and versions shown below. I get Maven
hanging in the middle of a test. When I investigate what's going on using
jps and jstack I get the following results which looks like an issue with
hsqldb .

 

TIA,

Best regards,

Giovanni

Re: Maven hangs while using hsqldb and eclipselink

Posted by Ron Wheeler <rw...@artifact-software.com>.
It looks like your test is hanging inside your code.

What is your question?
