That is strange. Can you give us some more information?

How exactly did you install icedtea/openjdk?

Was is it a precompiled package, if so from where?
If not, how did you configure and compile from source?

Do other opensuse users have the same issue?

What is the exact command given and output?
Both for the failing and the working -Xmx1m -version case?
(Best to copy/paste the command line completely, any output, including
errors, stacktraces and the output of -version is interesting.)

Thanks,

Mark
