问题
I'm trying to verify "on the fly" generated bytecode!
I already had several attempts, one attempt was to compile my classes in runtime with the eclipse compiler another was to compile from memory as mentioned here:
Compile From Memory
First results looked okay but I'm still not a 100% sure if the verification process is truly valid according to the JAVA 6 guidelines and security measurements as well to normal OOP Models.
Any better way on how to verify bytecode?
回答1:
If you load the generated bytecode using a standard class loader, the bytecode verifier of the JVM will verify (make sure it type checks, never falls of the "edge" of a method and so on) the bytecode for you.
回答2:
You can use the class verifier provided by the ASM toolkit. That does not require actually loading the classes by the JVM, and gives you more detailed verification error reports.
