From Kotlin's point of view, everything in annotation classes is non-abstract. A class inheriting from an annotation has a non-abstract fake override for each property of the annotation class constructor. But because members of annotation classes themselves were considered as abstract in the bridge-generating code (see DescriptorBasedFunctionHandle.isAbstract), there was a situation where a concrete fake override has only one declaration among overridden descriptors and it was abstract. This situation is invalid (a concrete fake override must have exactly one concrete super-declaration), therefore an exception was thrown. The fix is to avoid considering annotation class members abstract for the purposes of bridge generation. It's reasonably safe because no bridges should be ever generated for annotation subclasses anyway, because annotations can only have members with simple return types (final and non-generic). Note that in KT-19928, the problem is reproducible because of an incorrect "inexact analysis" in light classes where "Target" is resolved to an annotation class kotlin.annotation.Target. This behavior of the analysis in light classes seems to do no harm otherwise, so it's not a goal of this commit to change anything in that regard #KT-19928 Fixed
