PH67382: cjbuild and the compiler fail to manage long package names correctly, and to diagnose dynamic length JAVA-SHAREABLE items

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• With longer cjbuild --pkgname's various failures can occur as
  cjbuild performs package name substitutions, including
  generating bad names, I/O errors (IGYLI4055-E A permanent I/O
  error occurred on SYSIN or an HFS source record was longer than
  80 characters.) or IS RECURSIVE related issues (eg. IGYDS1515-E
  The "THREAD" compiler option was in effect but a "RECURSIVE"
  clause was not specified on the "PROGRAM-ID" paragraph)
  
  Dynamic length items are not supported under JAVA-SHAREABLE,
  but the compiler is generating empty classes rather than an
  error message indicating that dynamic length items are not
  supported.

Problem summary

• ****************************************************************
  * USERS AFFECTED: Users of Enterprise COBOL 6.4 using the      *
  *                 cjbuild utility to build a DLL for a         *
  *                 COBOL/Java interoperable application where   *
  *                 one or both of the following is true: 1) the *
  *                 application consists of at least one COBOL   *
  *                 program containing a data item defined with  *
  *                 the DYNAMIC clause and the data item is      *
  *                 under the scope of a JAVA-SHAREABLE          *
  *                 directive. 2) the cjbuild utility is invoked *
  *                 with a value for the -p/--pkgname option     *
  *                 that is long enough to result in some of the *
  *                 lines of the generated stub program to be    *
  *                 longer than 72 characters.                   *
  ****************************************************************
  * PROBLEM DESCRIPTION: 1. cjbuild fails due to a compile-time  *
  *                      error when compiling generated file     *
  *                      strg.java due to incorrectly generated  *
  *                      Java code that resulted from the        *
  *                      presence of the dynamic-length item     *
  *                      that was not supported. 2. cjbuild      *
  *                      fails due to a compile-time error from  *
  *                      the COBOL compiler when compiling one   *
  *                      of the stub files. The error is caused  *
  *                      by a line that is longer than 72        *
  *                      characters being continued incorrectly. *
  ****************************************************************
  * RECOMMENDATION: Apply the IBM-provided PTF.                  *
  ****************************************************************
  1. While it is documented that data items defined with the
  DYNAMIC clause cannot be shared with Java, the compiler was not
  handling this restriction properly. 2. cjbuild substitutes the
  user-specified package name into the stub source code before
  compiling it but was not always properly continuing lines that
  were longer than 72 characters.
  

Problem conclusion

• 1. The compiler was updated to ensure that dynamic-length
  elementary data items are never attempted to be shared with
  Java, and an informational message is now generated whenever
  such an item is ignored by JAVA-SHAREABLE. 2. cjbuild was
  updated to ensure that it correctly continues lines longer than
  72 characters in stub file code.
