So rather than fetching the system value, we can search for one of these paths: * /etc/alternatives/java_sdk/bin/java * /etc/alternatives/java_sdk/jre/bin/java * /etc/alternatives/jre/bin/java ----- Also found another bug: If you select a Specific Java VM, then click back to Default Java VM, then Specific Java VM again, then click back to Default Java VM a second time, here's what ends up in your devstudio.ini file: {code} $➔ cat studio/devstudio.ini -vm /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-8.b14.fc24.x86_64//usr/lib/jvm/java-1.8.0-openjdk-1.8.0.121-8.b14.fc24.x86_64 ... {code} -- This message was sent by Atlassian JIRA (v7.2.3#72005)
