Issue Description:
In non-exec-model,
Where Fact.value1 and value2 are both BigDecimal,
when $fact : Fact( $value1 : value1, $value2 : value2 ) then $value1 = 5; $total = $value1 + $value2;
this rule fails with
Exception executing consequence for rule "Rule 1" in com.example.reproducer: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.math.BigDecimal (java.lang.Integer and java.math.BigDecimal are in module java.base of loader 'bootstrap')

$value1 = 5; makes $value1 as Integer type.
exec-model has no issue because `5` is coerced to a BigDecimal.

- Run without an Exception.
- Likely meet with the exec-model behaviour
