This means it was compiled with Java 7, and likely you're running and
earlier Java.  A few options:

1. We modify the CMake build to specify -source and -target when
compiling the Java interface.

2. We can require Java 7.

3. Both #1 and #2

I think we should do #1 regardless.  #2 is complicated. The reason I
would suggest #2 is that Java 6 is not really supported anymore by
Oracle, and that Java 7 has been available for a while now and is
available on all of the big platforms.

Thoughts?

Thanks Steve, I have installed Java 7. It's ok now. I don't compile csound myself, thus either the Windows installer specifies which java version has to be used, or Java 7 has to be recommended. 

I have another issue now with this csound version. With the following arguments ="-d -m0 -g -iadc2 -odac2 -b64 -B256", the following message "N 4096 0" is displayed every x seconds (I didn't measure it), and the volume is extremly low. Csound tells 0dBFS level = 32768.0, and this is what I am expected in the orchestra. I don't put a  0dBFS statement in the orchestra.

Any ideas?

Hi Jean-Pierre,

Could you file a bug so that we can track this one?  Particularly I
think it should mention specifying what -source and -target to use in
the wrapper compilation in CMake, as well as updating documentation
and mentions of the Java wrapper to use Java 7.

Thanks!
steven
