If the fix is from the zlib project, then ignore the following, since it’s their code.
In Deflater.c: the existing significant code duplication between the arms of the if-else gives one pause. E.g., in the new file, compare lines 148/183 and 155/190. Might be bugs lurking at 183 and 190.
In deflate.c: the old code had “s->last_flush = Z_NO_FLUSH”, the new has “-2”. Should “-2” be symbolic instead?

Looking to fix a recent regression that appeared in 8u151. Thanks goes
to Sherman for the src patch. Paul Hohensee has also helped by provided
some test code. I've been able to modify an existing test to mimic the
behaviour seen with FlushableGZIPOutputStream which is found in Tomcat 7.x.
Sherman is working on a patch for JDK 10. For unix OSes, JDK 10 operates
with the zlib version found on the OS.
