Flash debugging throws errors inside try-catch

I get an acception thrown on

Type.resolveClass(className)

(inside the Type code in flash’s libraries - \HaxeToolkit\haxe\std\flash_std\Type.hx)
If it does not have a class with that name instead of going into the catch clause.
looks like the try-catch is just not working only on flash…
on other targets this works as expected.

anyone has any idea why that happens?

It seems to be in another try/catch?
