#  @test

#  @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
