------------------------------------

             Summary: Problem with the equals operator
                 Key: GROOVY-10899
                 URL: https://issues.apache.org/jira/browse/GROOVY-10899
             Project: Groovy
          Issue Type: Bug
    Affects Versions: 4.0.7
            Reporter: Damir Murat


I'm unsure if this is a general problem or just something with Uom ([https://github.com/unitsofmeasurement]) reference implementation.

However, in the following script, the last assertion fails when it should not. I can't tell why, but the equals operator does not end in calling an {{equals()}} method in {{tech.units.indriya.AbstractQuantity}} class as it should. 
 
{code:java}
@Grab('javax.measure:unit-api:2.1.3')
@Grab('tech.units:indriya:2.1.3')

import javax.measure.Quantity
import javax.measure.Unit
import javax.measure.quantity.Mass
import tech.units.indriya.quantity.Quantities
import tech.units.indriya.unit.Units

Quantity<Mass> quantity1 = Quantities.getQuantity(10, Units.KILOGRAM)
Quantity<Mass> quantity2 = Quantities.getQuantity(10_000, Units.GRAM)

println "$quantity1 (${Integer.toHexString(quantity1.hashCode())})"
println "$quantity2 (${Integer.toHexString(quantity2.hashCode())})"

assert quantity1 !== quantity2
assert !quantity1.equals(quantity2)

// Should not fail, but it does
assert quantity1 != quantity2
{code}
