Please review this small fix and new test. Also, I need a sponsor for 
this fix, who can push it.

In this fix logic for stripped_argname was put into "if (arg_len <= 
BUFLEN)" statement. stripped_argname is used only to check is option is 
newly obsolete. Since valid VM option should be not bigger than 255 
characters(BUFLEN value), then obsolete_jvm_flags contains only options 
with strlen <= BUFLEN.
