when i run my program today ,which want to copy someting from a place to another,my tool :eclipse,pops up a small window,reading:
io.FileCopy at localhost:1534 contains obsolete methods
the reason:The virtual machine was unable to remove all stack frames running old code from the call stack.The virtual machine is not supplying the debugger with valid date or those frames.Stepping into these obsolete frames may be hazardous to the target virtual machine.
-----------------------------
I don't kown the meaning ,and ,i don't know the reason,please tell me,thank you!
