# @summary Netbeans Fix and Continue crashes JVM
# @author Jim Holmlund/Swamy Venkataramanappa
# @key intermittent
# @run shell RedefineClearBreakpoint.sh
# The failure occurs after a bkpt is set and then cleared
# after a class redefinition, in a method that was EMCP.
# This sequence creates a state in which subsequent operations
# such as accessing local vars via JVMDI, can cause a hotspot crash.
# These are variables that can be set to control execution
