Compile error with Mac (UDPMavLinkPort.java:107: cannot find symbol)

Hi, I'm trying to compile the project on my Macbook Pro (Mavericks) and I got this compilation error:

carmix$ ant
Buildfile: /Users/carmix/Documents/jMAVSim/build.xml

make_dirs:

compile:

BUILD FAILED
/Users/carmix/Documents/jMAVSim/build.xml:20: Compile failed; see the compiler error output for details.

Could you help me?

The build failed because I had JDK 8 installed, with JDK 7 no problems!
