 #
 # HotSpot Virtual Machine Error, assertion failure
 # Please report this error at

 # assert(_default_stack_size == nt_hdrs.OptionalHeader.SizeOfStackReserve, "stack size mismatch - os::current_stack_size() vs. executable headers")
 #
 # Error ID: D:/BUILD_AREA/jdk142-update/ws/fcs/hotspot\src\os\win32\vm\os_win32.cpp, 2410
