NullPointerException in mvel MathProcessor with equality check when null property is on right side

*Consider Sample Rules*

rule "test id and name matches"
when
SomeDataHolder(id == anotherId, fullName == "lorem ipsum");
then
ruleResponse.add("lorem");
end

rule "test name matches"
when
SomeDataHolder(fullName == "dolor sit");
then
ruleResponse.add("dolor");
end

=====================================
*Test Input Parameters*

// Case 1: id and anotherId present
SomeDataHolder someDataHolder = new SomeDataHolder();
someDataHolder.setId(1234L);
someDataHolder.setAnotherId(1234L);
someDataHolder.setFullName("lorem ipsum");

// Case 2: id and anotherId both not present
SomeDataHolder someDataHolder = new SomeDataHolder();
someDataHolder.setFullName("dolor sit");

// Case 3: only id present (RHS null)
SomeDataHolder someDataHolder = new SomeDataHolder();
someDataHolder.setId(1234L);
someDataHolder.setFullName("dolor sit");

// Case 4: only anotherId present (LHS null)
SomeDataHolder someDataHolder = new SomeDataHolder();

someDataHolder.setAnotherId(1234L);
someDataHolder.setFullName("dolor sit");
=====================================

Using Drools 7.67.x or 8.32.0.Final there is a runtime exception:
