Thanks alot for taking note of this, Alexei!

By the way, IBM VME makes the same mistake.

Here's the similar issue for IBM VME: HARMONY-5200.

The test and the fix

[Vasily Zakharov]

Alexei, thank you very much for the quick fix, it seems to resolve the problem with XStream.

I just wonder it it was right to remove the null check that previously existed in commented code...

[Alexey Varlamov]

Vasily observed right, specification states that only non-static final fields can be modified.

Thanks, guys. I tried to modify a static field on RI and got
java.lang.IllegalAccessException: Field is final
