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