Cannot call modulo operator (%) on BigDecimal types

It looks like org.codehaus.groovy.runtime.typehandling.BigDecimalMath does not override the default mod() method from the abstract org.codehaus.groovy.runtime.typehandling.NumberMath

new BigInteger(5)%2 //ERROR
new BigDecimal(5.5)%2 //ERROR
5.5%2 //ERROR
new Double(5.5)%2 //OK
new Integer(5)%2 //OK
5%2 //OK

Caused by: java.lang.UnsupportedOperationException: Cannot use mod() on this number type: java.math.BigDecimal with value: 5.5
