Minimserver.sh cannot be started on qnap

[Rairwave]

As a big fan of Minimserver, I am installing Minimserver on my neighbor's QNAP nas.

However I get the following error:
MinimServer start error: /etc/init.d/minimserver.sh: line 84: /usr/local/jre/bin/java: cannot execute binary file

and then:
MinimServer status set to disabled.

With minimwatch I can't see the actual log and in the /share/MD0_DATA/.qpkg/MinimServer I can't find it either.

Any suggestions?

(QNAP TS-569L 3.8.3 Build 20130426 and minimserver 0.7.2)
