[kaffe] Exception running javasqlite on kaffe for arm architecture

I'm trying to run sqlite using the java wrapper at 
http://www.ch-werner.de/javasqlite/ on an arm linux target using kaffe
1.1.7 and jamvm.

It appears that I'm having a problem with the JNI layer. I am able to 
run $sqlite3 from the command line, creating/editing database files with 
no problems. When I run it as a java app:

kaffe -jar sqlite.jar data.db

I get an exception:
kaffe-bin: exception.c:106: vmExcept_setJNIFrame: Assertion `fp != 
(JNIFrameAddress)0' failed.

Oddly, it fails the first time when it tries to open the database, but 
the database file is created. the next time it fails when I try to do a 
select on a table on the database, with the same exception.

I followed the instructions to cross compile sqlite and the java 
wrappers for our arm target, and don't see anything obvious that might 
be causing this. Just wondering if anyone has come across this issue before.

Lastly, the versions I built for the x86 target run fine on the x86 
kaffe and jamvm.

gcc version is 3.3.1
kernel is Linux version 2.4.20__mvlcee31-omap730_gsm_gprs 
(mic at mic-desktop) (gcc version 3.3.1 (MontaVista 3.3.1- 
2004-10-08)) #1 Thu Nov 29 16:32:50 HKT 2007
