Does lectora publish Java (not javascript)

Hey I wondered if any of you guys could help me answer a technical question,

I am looking at a clients specification which details that the LMS supports "Java: 1.5.0.04".

I was wondering if Lectora publisher x.4 or x.5 publishes any Java and if so would it be any higher than this. I am presuming this is Java rather than JavaScript?

Any help is greatly appreciated.

Regards

Alan
