// SI-4560 (and SI-4601): Reflection caches are expected in the wrong classfiles
// with various differing constellations of self-types. This leads to runtime exceptions
// when the reflection caches are accessed. This tests both reflection cache accesses
// for structural type method invocations (`y.f()`) (SI-4560) and accesses to symbols which are
// handled similarly (SI-4601)

// TEST 1
// self-type is other trait
