Realm, la initialization de una matriz de cadena vacía devuelve "Tipo no soportado java.lang.String " en la compilation

Intento inicializar una matriz de cadenas vacía en una class de Kotlin, sin embargo, la syntax para esto parece estar escapándome, he comprobado los documentos de Kotlin y creo que lo estoy haciendo de la manera correcta, pero siempre termino con el siguiente post cuando se comstack:

Error:Execution failed for task ':core:compileDebugJavaWithJavac'. > java.lang.IllegalStateException: Unsupported type java.lang.String[] 

Intenté con los siguientes methods para inicializarlo, Android Studio no muestra ninguna línea roja en ninguno de estos.

 var categories = emptyArray<String>() var categories = arrayOf<String>() var categories: Array<String> = emptyArray() var categories: Array<String> = arrayOf() 

Parece ser un error, curiosamente está afectando a mi configuration de Kotlin previamente estable en AS 2.3.2, y de nuevo extrañamente, obtengo el mismo error de compilation cuando trato de crear lists de cadenas.

Así que parece ser un error específicamente en mi computadora portátil, estoy ejecutando exactamente el mismo código en mi escritorio usando la misma versión de AS, en el mismo proyecto, todo es idéntico y, sin embargo, comstack.

Muy bien, el error ahora está afectando a mi escritorio donde estoy usando Java regular, ni siquiera Kotlin, aquí está la stack stack de gradle:

No parece ser un complemento o un problema de la biblioteca, dejé todo atrás a la versión antes de manera individual y el problema aún ocurrió.

Entonces, en caso de que alguien se encuentre con este mismo problema, es debido a Realm, si extiendes RealmObject no puedes tener una matriz String o una list de cadenas, así que tienes que usar un pequeño contenedor como el siguiente:

 public class RealmString extends RealmObject { public String string; } 

Entonces, lo siguiente funciona:

 public RealmList<RealmString> strings; 

Espero que esto ayude a alguien más en el futuro.
