Having two Entities which are identical, except naming of properties.

@Entity(tableName = "working_entity")
data class WorkingEntity @Ignore constructor(
    @PrimaryKey
    var id: Long,
    // Why does this work?
    var otherName: Boolean? = null
) {
    constructor() : this(
        0, null
    )
}

@Entity(tableName = "test_entity")
data class TestEntity @Ignore constructor(
    @PrimaryKey
    var id: Long,
    // Why does this property not work
    var isMultiSelect: Boolean? = null
) {
    constructor() : this(
        0, null
    )
}

For both entities I provided a simple dao offering a simple getAll() function. The dao for WorkingEntity is generated properly, the dao of TestEntity not.

The main difference I noticed is the following part inside the ..Dao_Impl:

For TestEntity:

.....
if (_cursor.isNull(_cursorIndexOfIsMultiSelect)) {
        _tmp = null;
    } else {
        _tmp = _cursor.getInt(_cursorIndexOfIsMultiSelect);
    }
    _item.isMultiSelect = _tmp == null ? null : _tmp != 0;
.....

For WorkingEntity:

.....
    if (_cursor.isNull(_cursorIndexOfOtherName)) {
      _tmp = null;
    } else {
      _tmp = _cursor.getInt(_cursorIndexOfOtherName);
    }
    _tmpOtherName = _tmp == null ? null : _tmp != 0;
    _item.setOtherName(_tmpOtherName);
.....

The build is failing with error isMultiSelect' has private access in 'com.example.TestEntity'. We see that for WorkingEntity a setter is used instead of property access.

The error is easy to work around, but weirdly it seems to be caused by property naming. I've attached a simple project which reproduces that error.
