      Description



      Name: laC46010 Date: 10/17/96


      In some cases compiler sorts its error messages differently
      for the same source files. It seems it may depends on
      some external reasons such as CLASSPATH value for example.

      Such undeterministic behaviour of the compiler prevents
      its testing using "golden" files.

      A log below shows that an error message for "clss00403_a.java"
      is reported first in order when CLASSPATH si not set and
      as second when CLASSPATH is set.

      The same undeterministic behaviour can be seen also running
      other JCK's test case: "intf00403".
