PH28480: NULLPOINTEREXCEPTION IN IDZ DUE TO MISSING MEND STATEMENT IN ASSEMBLER MACRO

APAR status

• Closed as program error.

Error description

• In IBM Developer for z (IDz) we get a NullPointerException (NPE)
  if an assembler macro is not properly terminated with a MEND
  statement.
  
  The Assembler itself gives a severity 12 error message -
  "ASMA119S Too few MEND statements in COPY code" but IDz gives a
  java.lang.NullPointerException at
  com.ibm.dmh.scan.classify.utils.FileTypeClassification.classifyA
  sm(FileTypeClassification.java:51)
  
  sample macro to illustrate the problem -
  
           MACRO
           TESTMAC1 &BUILD=NO
           LCLA  &C                 TEST VAR
  &C       SETC  'TEST1'            SET TEST VAR
  
  Note that SETC is the last statement; it is not followed by
  MEND.
  

Local fix

• Manually set the file type to ".mac"; then it opens okay, and
  gives a warning message ("Expecting MEND") instead of NPE.
  

Problem summary

• NPE caused by code downstream, outside of product team.
  

Problem conclusion

• Updated classify-scanner component to latest.
  

Temporary fix
