Exception: kotlin.String cannot be cast to java.lang.String

PHPStorm 8.0.2

This exception occurs several times, but I couldn't find out what the preconditions are.

Looks like null safety interop was given hard to understand errors. I think this was a null pointer exception.

I added a guard in the jar https://github.com/pbyrne84/DynamicReturnTypePlugin/raw/master/deploy/DynamicReturnTypePlugin.zip

Sorry it took so long

Thanks for the updated plugin. I'll keep testing this for a while and will report back here. (might take some days as well though)

[pbyrne84]

I'll mark this as closed, feel free to give me a shout if it didn't work.

I have never got this but I have been doing very little php lately (mostly Scala) so my monkey hands have been away from from causing errors in my plugin.
