vararg Deprecation: inner classes of generic classes extending Throwable 38 Inner classes of generic types that inherit from Throwable could violate type-safety in a throw- catch scenario and thus Serializable and can now be used in serializable hierarchies. The Closeable.use function calls Throwable.addSuppressed when an exception is thrown during closing the resource after some other exception — — Floating point to bits conversions — — Regex is now serializable Closeable.use calls Throwable.addSuppressed if available JVM Backend Constructor calls normalization — — 41 preserve-class-initialization
