I'd like to backport JDK-8190753 to jdk15u for parity with jdk17u.

The original patch applied with minor changes:

- eliminated using of instanceof pattern matching feature that is disabled bt default

The functionality was tested with accompanying

./test/jdk/jdk/nio/zipfs/LargeCompressedEntrySizeTest.java
./test/jdk/jdk/nio/zipfs/ZipFSOutputStreamTest.java

Regression: jdk_tier2
