[wildfly-dev] WildFly 8.1.0.CR1 on OpenShift

Wed Apr 23 09:10:02 EDT 2014

Farah,

I've been looking at this some more, and the marker for Java just toggles
back and forth between Java 6 and Java 7. If the Java 7 marker is not
present, then a cartridge just defaults back to Java 6.

But you still have to have the version of Java installed on the gear in
order to toggle back and forth.

Here are the contents of the /usr/lib/jvm directory on the gear where
OpenShift online installed my Wildfly 8.1
cartridge ...

I truly think the answer is that the gear needs to add Java 8 SE in order
for the Wildfly cartridge to be able to use it. And the Wildfly cartridge
will then need to be updated to respond to a Java 8 marker..
