Standard Working Directory for Apple PList obviously is the AppRoot directory

otherwise something like this without a WorkingDir key wouldn’t work:

```
    <key>Java</key>
    <dict>
      <key>MainClass</key>
      <string>main.class.name</string>
      <key>JVMVersion</key>
      <string>1.6+</string>
      <key>ClassPath</key>
      <array>
        <string>$JAVAROOT/library1.jar</string>
        <string>lib/library2.jar</string>
      </array>
    </dict>
```

where `lib/` dir is relative to APP-package
