icedtea-6-jre-cacao 6b24-1.11.1-4ubuntu2 (amd64 binary) in ubuntu quantal

 The package provides an alternative runtime using the Cacao VM and the
 Cacao Just In Time Compiler (JIT). This is a somewhat faster alternative
 than the Zero port on architectures like alpha, armel, m68k, mips, mipsel,
 powerpc and s390.
 .
 The VM is started with the option `-cacao'. See the README.Debian for details.
