This code appear to have been initially introduced with the JDK 7 implementation of JSR 292, which implemented different ways of adapting to and from generic types than the current code: https://bugs.openjdk.java.net/browse/JDK-6839872 Many uses (possibly all) were removed in https://bugs.openjdk.java.net/browse/JDK-6983728 (8-b01) where adapters were reworked. This was backported to 7, so the code I'm removing here is probably dead in all active releases. ------------- PR: https://git.openjdk.java.net/jdk/pull/3075
