https://bugs.openjdk.java.net/browse/JDK-8058293 http://cr.openjdk.java.net/~vlivanov/8058293/webrev.00
Bit set computation in MHs.findFirstDupOrDrop/findFirstDrop is incorrect due to widening primitive conversions (int -> long) taking place. The fix is to explicitly use long where needed.
Also, fixed a case when reorder represents a permutation (zeroPos == newArity).
Testing: jck (api/java_lang/invoke), jdk/java/lang/invoke, jdk/java/util/streams w/ "-ea -esa" and COMPILE_THRESHOLD={0,30}
Thanks! Best regards, Vladimir Ivanov
