There are cases where inLen is known to be smaller than PARALLEL_LEN and is a waste of a check, such as merging with the ibuffer to create one block. Also moving it into EncryptOp would always mean an additional check and maybe an unnecessary jump to another method. I did that for doFinal, because gctr/ghash.doFinal() needs to was no extra checks. ------------- PR: https://git.openjdk.java.net/jdk/pull/4019
