The compiler has a phase ordering problem. Escape analysis runs before wrapper generation. When a generated wrapper calls a method defined in a different package, if that call is inlined, there will be no escape information for the variables defined in the inlined call. Those variables will be placed on the stack, which fails if they actually do escape. There are probably various complex ways to fix this. This is a simple way to avoid it: when a generated wrapper calls a method defined in a different package, treat all local variables as escaping. Fixes #9537.
