JDK-4759491 fix has introduced in b94 following changes in public API.
Namely, following public fields have appeared in java.util.zip.ZipConstants interface:

 /*
  * Extra field header ID
  */
static final int EXTID_ZIP64 = 0x0001; // Zip64
static final int EXTID_NTFS = 0x000a; // NTFS
static final int EXTID_UNIX = 0x000d; // UNIX
static final int EXTID_EXTT = 0x5455; // Info-ZIP Extended Timestamp

This affects following classes implementing directly or indirectly java.util.zip.ZipConstants interface:
- class java.util.jar.JarEntry;
- class java.util.jar.JarFile;
- class java.util.jar.JarInputStream;
- class java.util.jar.JarOutputStream;
- class java.util.zip.ZipEntry;
- class java.util.zip.ZipFile;
- class java.util.zip.ZipInputStream;
- class java.util.zip.ZipOutputStream;

As a result classes above has obtained public fields shown above.

JCK assumes that this needs to be CCC approved.
