JDK-8268435 - (ch) ChannelInputStream could override readAllBytes
Description
JDK-8268435 contains a cut-and-paste error which calls readNBytes() from the readAllBytes() implementation:

        if (!(ch instanceof SeekableByteChannel sbc))
            return super.readAllBytes();

https://github.com/openjdk/jdk/commit/0786d8b7b367e3aa3ffa54a3e339572938378dca#diff-21e4ff89fd54955e45fcd085ae8c08033b6c92de7f98ab0c836d4f754117ececR171

Since IntputStream.readAllBytes() calls readNBytes() again, this results in a stack overflow (rather than incorrect data being returned).
