fx:Array tag could not be resolved to an ActionScript class.

Since this morning, I cannot compile my Apache Royale projects, the error is located when trying to use the Array class from the adobe fx package ...

```

```

Console log:

```
This tag could not be resolved to an ActionScript class. It will be ignored.

^

```

Reproduce the failure by compiling the supplied MXML example and confirm that the tag is ignored. Trace the compiler's MXML tag-to-ActionScript class resolution for the Adobe fx namespace; done means fx:Array resolves correctly and the example compiles without the reported warning.
