Java (openjdk7) Porting for ARM arria V (armv7) development kit

[Manjunatha Srinivasan]

Hi
I am new to Java and I need to port java (openjdk7) for my ARM board altera
arria V (armv7) development kit. Here are steps i followed:
 1. Checked out poky repo into dylan branch from git (I need to port on
poky dylan only)
 2. Checked out meta-java repo into master branch from github and add as
layer at bblyaer.conf.
 3. Then, did MACHINE changes for alter and added below one at local.conf:

PREFERRED_VERSION_openjdk-7-jre = "25b30-2.3.12"
PREFERRED_VERSION_icedtea7-native = "2.1.3"

#Sometimes the following is needed:
PREFERRED_PROVIDER_openjdk-7-jre = "openjdk-7-jre"


 4.  Generated the root filesystem image and booted it.
>From target, executed  "java" fails by throwing error as "Illegal
instruction" (SIGILL)
My linux kernel (3.10) is disabled for floating point neon. If this is
enabled java error thrown as "Segmentation fault"(SIGSEGV).

Here is  sample log:

Please help me out for porting procedure for java on ARM altera. TIA.
