PH69737: CAST BYTE TO DETECT MISSING FIELD ON CATALOGSEARCHFIELD

APAR status

• Closed as program error.

Error description

• Error Message: N/A
  .
  Stack Trace: N/A
  .
  The customer's application is testing signed byte (minimum value
  of -128 and a maximum value of 127) against (int) 0xFF, which is
  255. The decimal value of a 0xFF byte is -1, so the test fails
  when the bytes are set to (byte) 0xFF. Bytes are signed values
  in java, there is no unsigned byte so they see false instead of
  expected true.
  

Local fix

• N/A
  

Problem summary

• CatalogSearchField.isFixedMissing() does not detect field that
  is all 0xFF.
  The customer's application checks a field set to all 0xFF with
  CatalogSearchField.isFixedMissing(), which is expected to return
  
  
  true, but instead it returns false.
  

Problem conclusion

• So we are doing a cast and test against (byte) 0xFF to fix this
  issue.
