FakeTryCatch spells wrong in Case(FakeTryCatch and FAKETRYCATCH) Maybe don't matter

ItzSomebody commented 5 years ago

This would cause ClassNotFoundException to happen.

ItzSomebody commented 5 years ago

My sample says otherwise.

ghost commented 5 years ago

Finished. It seems no problems. http://prntscr.com/msit86 http://prntscr.com/msiqk6

and it' surprise that Jbyte can't edit it. http://prntscr.com/msiwc5

ghost commented 5 years ago

if there are any problems，i will solve it next week.

ItzSomebody commented 5 years ago

Doesn't run on Java 11 or Java 8 without turning the verifier off.

ItzSomebody commented 5 years ago

@ItzSomebody error log pls. I fixed it already. and see line 27. 5d3c727 boolean Crasher = false; and genHandler()

It create a fake temp class to handler it.

FAKE_Handler

Never said it was the same error.

While this works on Java 8, this still causes issues with Java 11.

@ItzSomebody Java11 checks the class name

could bypass by -noverify but anyway,the best way to fix it is to edit the handler's class name but this will turn this feature very weak.

So I prefer this feature for Java8 only. (Just add a tip for Users.They will judge it.)

ItzSomebody commented 5 years ago

If I was going to plan to let this repository to get away with "turn the verifier off", I would have done it already.

Edit: This PR was unmerged.

ghost commented 5 years ago

@ItzSomebody emm.Just set it Java8 only. and add a tip.
