Work around:
The reference bug is listed following:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4957990

In my case the solution was to edit the DOMAIN\bin\setDomainEnv.cmd file. The following modifications were made before the server would start as intended:

The -Xms and -Xmx values were increased;
the -XX:PermSize and -XX:MaxPermSize values were increased too
and lastly, but probably most importantly
the if "%JAVA_VENDOR%"=="Sun" (conditions were changed to if "%JAVA_VENDOR%"=="Oracle" ) in order to properly recognize my JVM.
