#25 jNetMap for OS X immediately crashing on start

[rxtc]

Hi,
I decided to test this nice and useful program on my Mac Pro running 10.10.3 Yosemite with Java 8u45. The OS X version of jNetMap-0.5.4-OSX (and also earlier OS X versions) pops up and crashes immediately, leaving this error message in console:

18.04.15 02:47:48,009 com.apple.xpc.launchd[1]: (com.apple.xpc.launchd.oneshot.0x1000000d.launcher[1422]) Service exited with abnormal code: 1

The general jNetMap-0.5.4.jar is running, but unfortunately not able to save or keep any preferences and settings. Please correct this OS X version bug. Thanks.
