  28 #  @summary Netbeans Fix and Continue crashes JVM
  29 #  @author Jim Holmlund/Swamy Venkataramanappa
  30 #  @run shell RedefineClearBreakpoint.sh
  31 
  32 #  The failure occurs after a bkpt is set and then cleared
  33 #  after a class redefinition, in a method that was EMCP.
  34 #  This sequence creates a state in which subsequent operations
  35 #  such as accessing local vars via JVMDI, can cause a hotspot crash.
  36 
  37 # These are variables that can be set to control execution
