VM crashes executing lang/EXPR/expr751/expr75101m7/expr75101m7_rt.html JCK test in *old* plugin on Solaris 10 sparc in firefox browser. This is not a regression, all jdk7 versions from fcs affected. VM crash occurs in any firefox version supporting old plugin. (2.0 and 3.5 checked.)

Test passes without issues in *new* java plugin.

Test passes when run in SingleJVM JCK mode without browser.
