Error while compiling under DebianGNU/Linux 8 (jessie) 32-bit

Hi to all
after last git pull I experienced the subsequent error while compiling vlc. In detail the problem arise while
compiling libbluray. Here is the log:
[javac] result = 31 * result + Float.hashCode(width);
[javac] ^
[javac] method Float.hashCode() is not applicable
[javac] (actual and formal argument lists differ in length)
[javac] method Object.hashCode() is not applicable
[javac] (actual and formal argument lists differ in length)

same error if I download libbluray alone (git clone http://git.videolan.org/git/libbluray.git) and attempt to compile.
How can I overcome?
regards
