[Jamvm-general] ExceptionInInitializerError with jamvm

[Juser <bha...@gm...>]

Hi,

I have been doing some experiments with JAMVM on Mips OCTEON Processor. 
Jamvm works perfectly fine when using O32ABI. But compiling Jamvm for N32ABI
(Optimized compiler from Cavium) isn't working and errors as below. 
GNU Classpath 0.98 version is being used here.

(i) Encountered segmentation fault in the first case and one of the post in
jamvm mailing list
 suggested to use libffi to getaway with the issue.

(ii) Tried enabling ffi and now jamvm loads and using verbose can see
classes loading properly
 but eventually resulted in below errors.

Both jamvm, classpath are installed in /usr/local directory.

Appreciate your help in this regard.

Thanks,
