#  @summary redefine and pop top frame from jdb gets assertion failure

#  @author Jim Holmlund/Swamy Venkataramanappa

#

#  The failure occurs with debug java when the pop deletes the

#  line that called the method which is being popped.

#  @run shell RedefinePop.sh

# assert(index<len, "should have found method")
