RELEASE NOTES:

core-libs/java.net:

    JDK-8273655: `java.net.FileNameMap.getContentTypeFor(fileName)` May Return a Different MIME Type for Certain Filenames

      The default, built-in filename map in the JDK has been updated to include additional filename
      to MIME type mappings. Along with the additions, existing mappings of `.gz` and `.zip` have
      also been updated. This can result in the default, built-in `java.net.FileNameMap` instance
      returning a different MIME type from the `getContentTypeFor(String fileName)` method than what
      it returned in previous JDK releases.
      
      `java.net.URLConnection.guessContentTypeFromName(String fname)`, which may use this default,
      built-in `FileNameMap` instance, thus may return a different value than previously.

core-libs/java.io:

    JDK-8285445: New System Property to Disable Windows Alternate Data Stream Support in java.io.File

      The Windows implementation of `java.io.File` allows access to NTFS Alternate Data Streams
      (ADS) by default. Such streams have a structure like “filename:streamname”. A system property
      `jdk.io.File.enableADS` has been added to control this behavior. To disable ADS support in
      `java.io.File`, the system property `jdk.io.File.enableADS` should be set to `false` (case
      ignored). Stricter path checking however prevents the use of special devices such as `NUL:`

core-libs/java.util.jar:

    JDK-8193682: Default JDK Compressor Will Be Closed when IOException Is Encountered

      `DeflaterOutputStream.close()` and `GZIPOutputStream.finish()` methods have been modified to
      close out the associated default JDK compressor before propagating a Throwable up the stack.
      `ZIPOutputStream.closeEntry()` method has been modified to close out the associated default
      JDK compressor before propagating an IOException, not of type ZipException, up the stack.
