I am struggling with StringBuilder. I have a common module which uses StringBuilder but I cannot call the function from the JVM module since 
java.lang.StringBuilder
does not seem to be the actual type of it. What is the actual type in JVM?

I have no expect/actual, I am having something like:
Copy code
fun foo(sb: StringBuilder){}
in common module and I want to call it from jvm module

kotlin.text.StringBuilder
Unfortunately I cannot search for implementations or rather intellij does not find them
it seems like they missed to add 
actual
to the type alias 
kotlin.text.StringBuilder
in the JVM module

Intellij doesn't see it, but doing a gradle build works
In common, I have a var declared as follows:
var sb : StringBuilder = StringBuilder()
In jvm:
sb = java.lang.StringBuilder()
Intellij flags it, but it'll compile
