Hi @zentol , thanks for taking time for reviewing :)
It was my original thought.
However turns out due to `Scala` supports `default value` in parameters, in
order to achieve same behaviour as Java, adding a new method is not working
here.
This is what currently Java has:
1. createLocalEnvironment()
2. createLocalEnvironment(Int)
3. createLocalEnvironment(Int, Configuration)
Before this PR, in Scala we have:
createLocalEnvironment(Int = defaultValue)
So a Scala user can access this method by `createLocalEnvironment()` or
`createLocalEnvironment(someValue)`.
If I add another method `createLocalEnvironment(Int = defaultValue, conf =
defaultValue)`, compiler will complain because at this moment
`createLocalEnvironment(someValue)` is ambiguous.
My opinion is by just adding a parameter with default value to existing
method, it doesn't change the existing way to access the method.
How do you think?
