Oh, yes.  j2sdk-1_4_2-doc/docs/tooldocs/linux/java.html says so.

Then the code in main.c

   752                          if (vmargs.classpath != NULL) {
   753                                  strcat (newcpath, path_separator);
   754                                  strcat (newcpath, vmargs.classpath);
   755                                  free (vmargs.classpath);
   756                          }
   757
   758                          /* set the new classpath */
   759                          vmargs.classpath = newcpath;

should be

   752                          if (vmargs.classpath != NULL) {
   755                                  free (vmargs.classpath);
   756                          }
   757
   758                          /* set the new classpath */
   759                          vmargs.classpath = newcpath;

Anyway, the problem is that "free (vmargs.classpath);" fails here
if the environment variable CLASSPATH is set.  However meaningless
it may be,  CLASSPATH can be set when -jar is used.

My patch is expected to save this case.
