Hi

Java VM: OpenJDK Zero VM (14.0-b16 mixed mode linux-arm )
Zero + "mixed mode" in the version string indicated that the Thumb2 jit and
assembler loop optimizations are in use.

The thumb2 assembler addon are made up of about 16000 lines of handwritten
assembler that unfortunally are unmaintainable.
We will not be able to fix this bug since it would require a full time job to
keep the assembler addon in sync, resources that currently are not available.
Due to this maintainability issue the assembler addon will not get used on arm
when using the icedtea 1.9 release or later.

You can workaround this bug by passing -XX:+PrintCommandLineFlags to the VM it
will make the vm only use the Zero C++ implementation that are stable but
slower.
Other alternatives are to use cacao or jamvm instead of zero.

I can recomend you to upgrade to the latest icedtea version 1.10.1.
I have prepared binarys against debian squeeze armel that you can find here:

Cheers
Xerxes
