In 12.4 the internal representation of durations was changed to use a Java BigDecimal for the number of seconds in the duration. Comparison of durations uses BigDecimal.equals() to compare whether two durations are the same. However, the Java method BigDecimal.equals() compares the scale of the decimal value as well as its numerical value. Depending on how a duration was computed, two durations may have the same numerical value but have a different scale in their internal representations, which will cause them to compare incorrectly as being not equal.
