Consider casual HelloWorld class, which has infinite loop to print "HELLO". Sometimes, the following happens:

HelloWorld runs
JRD obtains its code
sout("HELLO") is present in the decompiled code
we use JRD to overwrite it to sout("BYE"), and upload new code
the running HelloWorld program's output changes, and now it prints "BYE"
if we request the bytecode again, usually it contains sout("BYE"), but sometimes it contains sout("HELLO")
in this moment, even less frequently, the HelloWorld will start to print "HELLO" again

I will inspect whether this isn't CPLC caching incorrectly.

judovana commented 3 years ago

nope. It is not CPLC fault. It happens also with direct binary change, or through jasm/jcoder.

I need to find a deterministic case.
