I'd like to backport JDK-8190753 to jdk11u for parity with jdk13u.

The original patch applied with minor changes:

- eliminated using of unsupported instanceof pattern match feature
- calls of unsupported FileSystems.newFileSystem(Path) and FileSystems.newFileSystem(Path, Map<String,?>) interfaces are replaced with FileSystems.newFileSystem(URI,Map<String,?>)

Functionality was tested with accompanying

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

Regression: jdk_tier2
