redefine¶
Load the external*.class
files to re-define the loaded peer class in JVM.
Reference: Instrumentation#redefineClasses
Notes: Re-defined classes cannot be restored. There are chances that redefining may fail due to some reasons, for example: there’s new field introduced in the new version of the class, pls. refer to JDK’s documentation for the limitations.
