#  @bug 4705330
#  @summary Netbeans Fix and Continue crashes JVM
#  @author Jim Holmlund/Swamy Venkataramanappa
#  @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
