RS00961: PROBLEMS WITH TESTS WITH BIGDECIMAL AND DECIMAL PRECISION, EQUALS UNORDERED TEST

WebSphere Operational Decision Management V7.5.0.2 Fix Pack

APAR status

• Closed as program error.

Error description

• Several problems were found with tests on BigDecimal and with
  decimal precision:
  1. When testing a BigDecimal ending with 0 against a BigDecimal
  that is not ending with 0, the test fails. For example, when
  testing if 12.20 equals 12.2, false is returned whereas it
  should be true.
  2. Testing of BigDecimal attributes in objects inside
  collections or arrays does not work. The tests always return
  false.
  3. Rounding with decimal precision is erroneous for numbers
  (BigDecimal, Double, Float) lower than 1. For example, when
  rounding 0.009 with a decimal precision of 2, 0 is returned
  instead of 0.01.
  4. Decimal precision is not taken into account for tests on
  collections and arrays of complex objects.
  5. The Equals Unordered test is erroneous for collections and
  arrays. Sometimes an exception is raised when there are too many
  possible matching values between the expected values and the
  observed values.
