Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.4 compiling and  *
  *                 running programs that use non-OO COBOL/Java  *
  *                 interoperability features, such as the       *
  *                 JAVA-CALLABLE and JAVA-SHAREABLE directives  *
  *                 or make calls to static Java methods using   *
  *                 the CALL statement.                          *
  ****************************************************************
  * PROBLEM DESCRIPTION: (1) Incorrect error message produced by *
  *                      the cjbuild utility (file not found)    *
  *                      when the interoperable application      *
  *                      includes a COBOL program that has       *
  *                      Java-shareable items but the program    *
  *                      itself does not contain the             *
  *                      >>JAVA-CALLABLE directive, which is not *
  *                      a requirement.                          *
  *                                                              *
  *                      (2) Not all name collision errors for   *
  *                      Java-shareable items were being caught  *
  *                      and reported.                           *
  *                                                              *
  *                      (3) The NOJAVAIOP option, which when in *
  *                      effect means there are no special       *
  *                      values for JAVAIOP suboptions (i.e.,    *
  *                      only defaults are used), was being      *
  *                      treated properly as the default form of *
  *                      the JAVAIOP option but could no longer  *
  *                      be specified explicitly.                *
  ****************************************************************
  * RECOMMENDATION: Apply the IBM-provided PTF                   *
  ****************************************************************
  The cjbuild utility was incorrectly expecting all COBOL programs
  in the application that contain Java-shareable items to also
  contain the >>JAVA-CALLABLE directive, even though that is not a
  requirement. The cjbuild utility was also not reliably reporting
  all cases where a name collision of Java-shareable items
  occurred
  (i.e., cases where different COBOL programs in the application
  have one or more 01/77-level Java-shareable items with the same
  name). Additionally, the NOJAVAIOP option, which just sets all
  JAVAIOP suboptions to their defaults, was not being accepted
  properly after the new NOJVMINITOPTIONS suboption was added.
  

Problem conclusion

• The compiler and the cjbuild utility were updated to address
  various usability and stability issues relating to the non-OO
  Java/COBOL interoperability feature.
