Comienza con DictionaryValuesWriter.java en fallBackDictionaryEncodedData, línea 284, y sigue las llamadas de fallback a través de DictionaryValuesWriter.java, FallbackValuesWriter.java y ColumnWriterV1.java. Determina la entrada que produce la ArrayIndexOutOfBoundsException reportada y verifica que la ruta de fallback la gestione sin la excepción, con cobertura de regresión si se identifica un punto de entrada de prueba existente.
