comment in lambda expression triggers a ParentNotInitializedException

[stefanleh]

It looks like comments in lambda expressions are a problem for 7.1.0 version of spoon lib.

Optional<Field> fieldConditionValueOptional = join.getConditions().stream().filter(condition -> //
            condition.getDescription().getName().equals(fieldName)
                    && (condition.getOperator() == EQUAL || condition.getOperator() == IS_EMPTY)
                    && condition instanceof FieldCondition)
                    .map(condition -> new Field(condition.getDescription(),
                            condition.getOperator() == EQUAL ? condition.getValue() : condition.getDescription().getInitialValue()))
                    .findFirst();

[surli]

Looks like we have several bugs related to comments in lambda. We already have #2763 open

[stefanleh]

I think this one can be closed as duplicate of #2763.

[stefanleh]

I've tested this with 7.5.0-beta-20 and there seems to be a regression.
Its exactly the same code from above.
