I just released mapjfx version 1.13.0 it should be found shortly at maven central, the artifact coordinates are:
<dependency> <groupId>com.sothawo</groupId> <artifactId>mapjfx</artifactId> <version>1.13.0</version> </dependency>
The source is available at GitHub.
The offline cache now can be configured with a collection of Strings (Java RegExp patterns) so that URLs matching any of these will not be cached.
Comments and contributions welcome.
