In some cases core dumped after
ZipInputStream.read(byte b[], int off, int len) call.
This bug has been fixed in jdk1.2fcs and may be closed
as such immediately.

Here is a sample demonstrating this bug:
------------------ Test11.java ---------------------
import java.util.zip.*;
import java.io.*;

public class Test11 {
    public static void main(String[] args) {
        try {
            ByteArrayOutputStream out = new ByteArrayOutputStream();
            ZipOutputStream jo = new ZipOutputStream(out);
            jo.putNextEntry(new ZipEntry("entry1"));
            jo.closeEntry();
            jo.close();
          
            ZipInputStream in = new
  ZipInputStream(new ByteArrayInputStream(out.toByteArray()));

            in.getNextEntry();
            int i = in.read(null, 0, 0);

            System.out.println("road bytes: " + i);
        } catch(IOException e) {
            System.out.println("IOException");
} catch(NullPointerException e) {
System.out.println("NullPointerException");
} catch(Throwable e) {
            System.out.println( "Unexpected "+e+" thrown" );
}
    }
}
