-<p>Prior to Java 16, the <code class="language-plaintext 
highlighter-rouge">java.util.zip.GZIPOutputStream</code> wrote a value of zero 
for the OS field
-in the header (byte index 9). 
-In Java 16, this was changed to a value of 255 to better abide by the GZIP 
specification. 
-Unfortunately, this means unparsed data using a GZIP layer might have a single 
byte difference,
-depending on the Java version used. 
-To avoid inconsistent behavior of test failures that expect a certain byte 
value this layer
-always writes a consistent header (header byte 9 of 255) regardless of the 
Java version.</p>
