String based parser: Linking objects not working on classes named starting by class_

[sync-by-unito]

Linking objects not working on classes which name starts by class_. This can be triggered on Realm-Java by

• directly setting an inner name;
• or setting LOWER_CASE_WITH_UNDERSCORES naming policy on a class whose name starts by Class. 

Trying query links on these classes would result in that the table can not be resolved:

"No property 'with_underscores' found in type 'with_policy' which links to type 'class_with_policy'"

It can be seen in the error with_policy should be class_with_policy.

Example:

Query

"parents.pascal_case = $0" $0 = 1

Class

@RealmClass(fieldNamingPolicy = RealmNamingPolicy.LOWER_CASE_WITH_UNDERSCORES)
public class ClassWithPolicy extends RealmObject {

    public static final String CLASS_NAME = "class_with_policy";
    public static final String FIELD_CAMEL_CASE = "camel_case";
    public static final String FIELD_PASCAL_CASE = "pascal_case";
    public static final String FIELD_M_HUNGARIAN = "hungarian";
    public static final String FIELD_ALLCAPS = "allcaps";
    public static final String FIELD_ALLLOWER = "alllower";
    public static final String FIELD_FIRST_CAPS = "first_caps";
    public static final String FIELD_WITH_UNDERSCORES = "with_underscores";
    public static final String FIELD_WITH_SPECIAL_CHARS = "internal_var";
    public static final String FIELD_CUSTOM_NAME = "a different name";
    public static final List<String> ALL_FIELDS = Arrays.asList(
            FIELD_CAMEL_CASE,
            FIELD_PASCAL_CASE,
            FIELD_M_HUNGARIAN,
            FIELD_ALLCAPS,
            FIELD_ALLLOWER,
            FIELD_FIRST_CAPS,
            FIELD_WITH_UNDERSCORES,
            FIELD_WITH_SPECIAL_CHARS,
            FIELD_CUSTOM_NAME
    );

    public String camelCase;
    public int PascalCase;
    public boolean mHungarian;
    public byte[] ALLCAPS;
    public Date alllower;
    public long FIRSTCaps;
    public ClassWithPolicy with_underscores;
    public RealmList<ClassWithPolicy> $_internalVar;
    @RealmField(name = "a different name")
    public String customName;

    @LinkingObjects("with_underscores")
    public final RealmResults<ClassWithPolicy> parents = null;
}

I can't figure out what this will translate into in Core terms. [~clemente.tort], can you provide a realm file based on this schema?

[~jorgen.edelbo] here it is:  [^default.realm]

I believe the issue is related to KeyPathMapping. We populate it using keypath_helpers.

➤ Jørgen Edelbo commented:

[~clemente.tort] What would be the actual mappings you would supply here?

[jedelbo]

I tried to reproduce error here #4508 but did not succeed. @clementetb can you see where I am mistaken?

[jedelbo]

At least I have now identified the root cause.

Changing status to investigate after the debug session we had.
