java.util.zip.GZIPConstants

[Sascha Brawer]

Hello,

while reviewing the constant field values in Classpath, I stumbled across
the following situation:

// Classpath
package java.util.zip;

interface GZIPConstants
{
  public static final int GZIP_MAGIC = 0x1f8b;
  public static final int FTEXT = 0x1;
  ...
}


public class GZIPInputStream
  extends InflaterInputStream
  implements GZIPConstants
{
  ...
}


public class GZIPOutputStream
  extends DeflaterOutputStream
  implements GZIPConstants
{
  ...
}



Now, according Sun's J2SE 1.4 Javadoc, one would expect the following:

// Spec
package java.util.zip;

public class GZIPInputStream
  extends InflaterInputStream
{
  public static final int GZIP_MAGIC = 0x1f8b;
  ...
}


public class GZIPOutputStream
  extends DeflaterOutputStream
{
  ...
}


Observations:

1. The spec requires GZIPInputStream.GZIP_MAGIC; Classpath inherits the
field from a package-private interface.

2. According to the spec, there should not be a GZIPOutputStream.GZIP_MAGIC.

3. According to the spec, there should not be a FTEXT anywhere.

Are any of these non-conformant?
