Re: [jbosstools-dev] Some questions about migrating to Java 8 and Mars

Hey Snjeza, That's an interesting thought. Add where exactly? To the eclipse.ini file? Or just for maven command line execution? When I add it to the build (mvn -U clean install -XX:-UseGCOverheadLimit) it fails at command line with some interesting errors. _______________________________ Brian Fitzpatrick (aka "Fitz") Senior Software Engineer, Tooling JBoss by Red Hat ----- Original Message ----- From: "Snjezana Peco" <snjeza.peco(a)gmail.com&gt; To: "Brian Fitzpatrick" <bfitzpat(a)redhat.com&gt; Cc: "jbosstools-dev jbosstools-dev" <jbosstools-dev(a)lists.jboss.org&gt; Sent: Thursday, July 23, 2015 3:07:11 PM Subject: Re: [jbosstools-dev] Some questions about migrating to Java 8 and Mars Try to add -XX:-UseGCOverheadLimit.
