Exceptions when installing Crowd

[Christian Schnetter]

Ubuntu 14.10, all updates.
Jira & Confluence installed without problems.

I get the following Errors:

Any help is hightly appreciated.

Unsupported major.minor version 52.0

Looks like you're trying to execute Crowd with an old JDK (<1.8). Please check your JAVA_HOME.
