[ https://issues.jboss.org/browse/JBTIS-571?page=com.atlassian.jira.plugin.... ] Andrej Podhradsky commented on JBTIS-571: ----------------------------------------- I was able to reproduce this issue on Fedora 22 and on Win10. The problem occurs only if the SwitchYard editor remains opened and then you restart the IDE. I also noticed that there is the same error (you can see this error only if you run the JBDS from command line) as the one reported at https://issues.jboss.org/browse/SWITCHYARD-2767 Note that JBDS 9.0.0.GA comes with JBDS-IS 9.0.0.Alpha2 and all components are still on early access. The mentioned issue is fixed in JBDS-IS 9.0.0.Beta1 which is available only in JBDS 9.1.0.Beta2 (the GA is coming soon). Nicolas, if you wish to use SwitchYard tooling without to the above issue, please follow these steps 1. Install JBDS 9.1.0.Beta2 or update your existing JBDS 9.0.0.GA from https://devstudio.redhat.com/9.0/development/updates/ 2. Install SwitchYard from JBoss Central (if you have the old one, please remove it and install it from JBoss Central again) (unfortunately, you cannot directly update the old SwitchYard tooling since there were changes in version format) -- This message was sent by Atlassian JIRA (v6.4.11#64026)
