I just released mapjfx version 1.7.0 it can be found at maven central, the artifact coordinates are:

  <dependency>
    <groupId>com.sothawo</groupId>
    <artifactId>mapjfx</artifactId>
    <version>1.7.0</version>
  </dependency>

The source is available at GitHub.

The library can now use a directory to cache the downloaded map images for later speedup and offline use. Detailed information can be found here.

Comments and contributions welcome.
