JBOSS Gothcha Java Version

Tags: JBOSS Gotcha

Ubuntu servers, such as those on the UHL network, have a tendency to default to Open-JDK Java, when updating. Some versions of Open-JDK do not work well with JBoss, leading to applications, and in fact the entire JBoss AS framework, failing to start correctly, often without meaningful error messages. If you detect such behaviour, check the version of Java being used by default by the system:

update-alternatives --config java

It may be that you need to re-install Sun Java JDK - and that to do so you need to edit /etc/apt/sources in order to re-enable the 'partners' repository.
