like this code

package ReportBug2

class A
    B b = new B()
    function get() returns int
        return b.get()
    static class B
        function get() returns int
            return 1

@Test
function test()
    new A().get()

unit tests result:

Running <ReportBug2:12 - test>..
    FAILED with exception: You encountered a bug in the interpreter: java.lang.RuntimeException: Null pointer dereference
... when calling A_get(0) in ReportBug2.wurst:6
... when calling A_get(5) in ReportBug2.wurst:6
... when calling A_get(4) in ReportBug2.wurst:13

Here are some compiler internals, that might help Wurst developers to debug this issue:
