Multiply(BigDecimal)
Computes a new duration whose value is factor times
longer than the value of this duration.

Returns
returns a non-null valid Duration object

Exceptions
if operation produces fraction in the months field.
if the factor parameter is
null.
Remarks
Computes a new duration whose value is factor times longer than the value of this duration.
For example,
"P1M" (1 month) * "12" = "P12M" (12 months)
"PT1M" (1 min) * "0.3" = "PT18S" (18 seconds)
"P1M" (1 month) * "1.5" = IllegalStateException
Since the Duration class is immutable, this method doesn't change the value of this object. It simply computes a new Duration object and returns it.
The operation will be performed field by field with the precision of BigDecimal. Since all the fields except seconds are restricted to hold integers, any fraction produced by the computation will be carried down toward the next lower unit. For example, if you multiply "P1D" (1 day) with "0.5", then it will be 0.5 day, which will be carried down to "PT12H" (12 hours). When fractions of month cannot be meaningfully carried down to days, or year to months, this will cause an IllegalStateException to be thrown. For example if you multiple one month by 0.5.
To avoid IllegalStateException, use the #normalizeWith(Calendar) method to remove the years and months fields.
