Do not consider Java 8 (1.8) to be Java 1

BlueMapGUI/lib/main_menu/settings/java/util_for_checking_java_path_version.dart

Line 32 in b00a39e

RegExp r = RegExp(r"\d+");

Here I extract the first number from the message, but Java 8 is also sometimes referred to as Java 1.8
Then, printing "Java 1 is too old" is a bit extreme...

Maybe I'll extract the first two parts and parse them as doubles..?

Or I could do a specific check for 1.\d
