Java Mode Migration

Hi all,

I have ported Java based Opendaylight Controller on PowerPc board and have
integrated JAVA on the same Powerpc architecture using meta-java.By default
it cam with Zero port support which only works in interpreter mode.

java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.12) (25b30-2.3.12)
OpenJDK Zero VM (build 23.7-b01, interpreted mode)

When I run takes approximately about 10 min for the
Controller to start properly.
However when i run it on x-86,it works fine.The Java -version at x-86 is as

java -version
java version "1.7.0_25"
OpenJDK Runtime Environment (IcedTea 2.3.10) (7u25-2.3.10-1ubuntu0.12.04.2)
OpenJDK Server VM (build 23.7-b01, mixed mode)

I noticed that the Java mode at x-86 is mixed mode whereas at that of my
board is interpreted mode.
Can this be the reason for delay in starting?
If yes suggest me how to migrate from inerpreted mode to mixed mode .
Also I need to enable Shark support on the board . Can any one please help
me with the procedure to compile JAVA with Shark support.

Or there is some another reason associated with that.

Please help regarding this.



Please help..
