Jdk9Application (JMRI API)

java.lang.Object
- apps.plaf.macosx.Application
- - apps.plaf.macosx.Jdk9Application

```
class Jdk9Application
extends Application
```
Wrapper for Apple provided extensions to Java that allow Java apps to feel more "Mac-like" on Mac OS X for JDK 9.
NOTE All use of this class must be wrapped in a conditional test that ensures that JMRI is not running on Mac OS X or in Try-Catch blocks. The easiest test is:
```
 if (SystemType.isMacOSX()) {
     ...
 }
 
```
A Try-Catch block will need to catch NoClassDefFoundError Failure to use one of these methods will result in crashes.
