#  @summary RedefineClasses gets assertion: "Should be a method entry in cpcache!"

#  @author jjh

#

#  @run shell/timeout=180 RedefineClasses.sh

# On windows, with b90, this gets this:

# assert(u2_at_bcp >= 0 && u2_at_bcp < old_cache->length(), "Bad cpcache index!")

#

# Error happened during: VM_RedefineClasses

#

# Error ID: D:/jdk1.4/hotspot\src\share\vm\prims\jvmdi_hotswap.cpp, 331

# On solaris, and on windows with 4559100 fixed, this test fails with:

#

# HotSpot Virtual Machine Error, assertion failure

# Please report this error at

# http://java.sun.com/cgi-bin/bugreport.cgi

#

# Java VM: Java HotSpot(TM) Client VM (1.4-internal-debug mixed mode)

#

# assert(old_cache->entry_at(u2_at_bcp)->is_method_entry(), "Should be a method entry in cpcache!")

#

# Error happened during: VM_RedefineClasses

#

# Error ID: M:\ws\m\b2\service_hs_baseline\src\share\vm\prims\jvmdi_hotswap.cpp, 335

# With -Xcomp on solaris this passes, but takes 2 minutes, thus the /timeout above.

# These are variables that can be set to control execution
