Renderscript GL crash in JB

[celavek]

I have some application which uses the Renderscript GL API.
It is based on the Fountain renderscript sample which was available
in the ICS SDK. My app is working fine in ICS but it crashes in JB.
I know the Renderscript GL API has been deprecated for 4.1 and it
will probably disappear in the future versions but I was expecting the
code to work nevertheless. Would appreciate If anyone could give
some pointers on what could be going wrong or maybe anybody does
know how would one tackle porting the Renderscript GL app to
Open GL - could not find anything on the net about that, not even in
the Google documentation which is quite surprising(a porting guide
would have been most welcomed along with the deprecation).
Attached is the crash log.

Thanks
