      The following steps of getting a Jar entry results in Hotspot VM error instead
      of an Exception being thrown.

      Way to reproduce the problem:

      1. Create a JarFile instance using any Jar file
      2. Get a Jar entry

      // This is a programming error.
      3. open the same Jar file for writing

      4. Get a Jar entry again

      I encountered this problem while working on an open source project (http://sourceforge.net/diduce) in a much more complex environment.

      The following a code snippet reproduces the problem using the
      jar file attached to this bug report.

      import java.util.zip.*;
      import java.util.jar.*;
      import java.io.*;

      class TestGetEntry {

          public static void main(String args[]) throws Exception {
               String jar_file_name = "java-classes.jar";
               String entry1 = "Methods.class";
               String entry2 = "Sanity.class";

               JarFile _input_jarfile = new JarFile (jar_file_name);
               JarEntry je = _input_jarfile.getJarEntry(entry1);
               System.out.println("entry name1:" + je.getName());

               FileOutputStream fos = new FileOutputStream(jar_file_name);
               JarOutputStream jout = new JarOutputStream(fos);

               je = _input_jarfile.getJarEntry (entry2);
               System.out.println("entry name2:" + je.getName());

      Note: the problem is reproduceable on 1.4.1, 1.4.2 as well as tiger b62.

      The Error log is more verbose with 1.4.2 vm
