TL;DR: you should not use +getSimpleName / getCanonicalName / isAnonymousClass / isLocalClass / isSynthetic. + + - Some methods in Java reflection assume a certain structure in the class names. Scalac + can produce class files that don't respect this structure. Certain methods in reflection + therefore give surprising answers or may even throw an exception. + + In particular, the method "getSimpleName" assumes that classes are named after the Java spec + http://docs.oracle.com/javase/specs/jls/se8/html/jls-13.html#jls-13.1 + + Consider the following Scala example: + class A { object B { class C } } + + The classfile for C has the name "A$B$C", while the classfile for the module B has the + name "A$B$". + + For "cClass.getSimpleName, the implementation first strips the name of the enclosing class, + which produces "C". The implementation then expects a "$" character, which is missing, and + throws an InternalError. + + Consider another example: + trait T + class A { val x = new T {} } + object B { val x = new T {} } + + The anonymous classes are named "A$$anon$1" and "B$$anon$2". If you call "getSimpleName", + you get "$anon$1" (leading $) and "anon$2" (no leading $). + + - There are certain other methods in the Java reflection API that depend on getSimpleName. + These should be avoided, they yield unexpected results: + + - isAnonymousClass is always false. Scala-defined classes are never anonymous for Java + reflection. Java reflection insepects the class name to decide whether a class is + anonymous, based on the name spec referenced above. + Also, the implementation of "isAnonymousClass" calls "getSimpleName", which may throw. + + - isLocalClass: should be true true for local classes (nested classes that are not + members), but not for anonymous classes. Since "isAnonymousClass" is always false, + Java reflection thinks that all Scala-defined anonymous classes are local. + The implementation may also throw, since it uses "isAnonymousClass": + class A { object B { def f = { class KB; new KB } } } + (new A).B.f.getClass.isLocalClass // boom + + - getCanonicalName: uses "getSimpleName" in the implementation. In the first example, + cClass.getCanonicalName also fails with an InternalError. + + - Scala-defined classes are never synthetic for Java reflection.
