java.util.zip.InflaterInputStream patch

[Mark Wielaard]

Hi,

I am slowly integrating the Intel Orp patches and had a question on the
following change:

* classpath/java/util/zip/InflaterInputStream.java: a small fix for
native zlib.

          fill();
+        if (len == 0)

+        }
+      }
        else
          throw new InternalError("Don't know what to do");
       }

When is this needed? GNU Classpath now contains a pure java
java.util.zip package so it doesn't seem to be necessary. When does this
situation that fill() returns zero bytes occur? If you have an example
zip file or other test case that shows the problem that would be greatly
appreciated.

Cheers,

Mark
