      Description

      StackFrameInfo::walker field is used to determine if the StackWalker retains Class reference and StackFrame::getDeclaringClass can throw UOE if no access.

      StackFrameInfo can have a bitmap and store the capability in the bitmap. The BCI is a short and the bitmap may just use the padding due to the alignment. This way it will save some memory footprint.
