Now, I tried to install only "SwitchYard" + "RT-Gov Client-only" and it works as expected (I didn't get the error), so I assume that you used this configuration.

Errors when starting FSW 6.0.0.GA from JBDS 8.0.2.GA with JDK 1.8 ----------------------------------------------------------------- Key: JBDS-3345 URL: https://issues.jboss.org/browse/JBDS-3345 Project: Developer Studio (JBoss Developer Studio) Issue Type: Bug Components: server Affects Versions: 8.0.2.GA Environment: Fedora 21 x86_64 JBDS 8.0.2.GA with Oracle JDK 1.8.0_25 and Oracle JDK 1.7.0_71 Reporter: Andrej Podhradsky Priority: Critical Attachments: compiler.png, console.png, errors.txt, error_log.txt, installed_jre.png, run.sh, runtime_jre.png, server.log FSW 6.0.0.GA supports java 6 and 7, so if we want to run this server on JBDS 8 with jdk 8 we need to add another jdk to the JBDS, e.g. jdk 7. But this doesn't work, see errors in the attached file. Moreover, we are not able to stop the server from IDE, the process is still alive and we have to kill it manually. Note that this happens only when we install JBDS 8.0.2 with jdk 8, if we install it with jdk 7 the server works fine.
