AirFoundation is an open research organization focused on Java runtime internals — we study what happens after javac compiles your source and before the CPU executes the result.
Our work spans three layers of the Java execution stack:
|
Inspect compiled behavior, protection layers, and transformed control flow. 0: aload_0
1: invokestatic #42
4: areturn |
Trace the boundary where managed Java enters native execution. mov rax, [rbp-08h]
test rax, rax
jne short loc_1402A |
Recover, analyze, and rewrite class-level instructions. ClassReader(bytes)
.accept(visitor, 0)
// ASM9 |
