gharl... groovy! slf4j! method returns an

@Nullable String

and the null is causing the logger to go bloosh! I'm going to assume that on my plugin (written in java) side, there's not much I can do other than say "don't do that"?

Cannot resolve which method to invoke for [class java.lang.String, null] due to overlapping prototypes between:
  	[class java.lang.String, class [Ljava.lang.Object;]
  	[class java.lang.String, class java.lang.Throwable]

this would fail in java as well, no? just cast the

null

to the correct type for the method signature you wish to invoke

it probably would, which is why I'm cursing at slf4j too
