> The class `GZIPOutputStream` extends `DeflaterOutputStream`, which is logical > because the GZIP encoding is based on ZLIB "deflate" encoding. > > However, while `DeflaterOutputStream` provides constructors that take a > custom `Deflater` argument supplied by the caller, `GZIPOutputStream` has no > such constructors. > > As a result, it's not possible to do entirely reasonable customization, such > as configuring a `GZIPOutputStream` for a non-default compression level. > > This change adds a new `GZIPOutputStream` constructor that accepts a custom > `Deflater`, and also adds a basic unit test for it and all of the other > `GZIPOutputStream` constructors, based on the existing test > `BasicGZIPInputStreamTest.java` which does the same thing for > `GZIPInputStream`.
