Throwing IllegalArgumentException is the correct way but it may break the
existing behavior. Consider the case where application code is like
zk.create(callBackHandler)` // call to create api and callback
handler is passed
doSomething();
- - - - // some more stuff
At present, if client pass null ACL parameter, the error will be handled by
callBackHandler and in application code doSomething() method will execute.
But if we throw IllegalArgumentException , then doSomething() method will
not execute. So it will change the existing behavior of application code.
Please suggest if we really need to handle this case.
