Exception on Initial Launch

[atomicdad]

Details:
terramaster-3.02.jar
Windows 11
java version "1.8.0_431"

java -jar .\terramaster-3.02.jar

Returns the following exception.

WARNING: Couldn't load properties : java.io.FileNotFoundException: terramaster.properties (The system cannot find the file specified)

I've tried a few things include giving it a blank terramaster.properties file, updating JRE to the version above, and downgrading to the 3.00 version. All fail to launch.

When I made a blank terramaster.properties that error went away but I get NoSuchMethodError exception.

Exception in thread "AWT-EventQueue-0" java.lang.NoSuchMethodError: java.lang.String.isBlank()Z

Not sure what the Z at the end of that is. I'm also really confused about what version of the Java runtime is the latest. Official JRE download gave me "Java 8" I believe. And after going down a rabbit hole of Oracle versioning it appears that is the latest.

Not sure what I'm doing wrong here.

yeah, there's definitely something wrong there...

$ java --version
openjdk 11.0.25 2024-10-15
OpenJDK Runtime Environment (build 11.0.25+9-post-Ubuntu-1ubuntu122.04)
OpenJDK 64-Bit Server VM (build 11.0.25+9-post-Ubuntu-1ubuntu122.04, mixed mode, sharing)

i haven't done windows in probably 20 years but i do remember a few dances with multiple versions of java or something being installed... IIRC i had to go into the control panel to the icon for it, open it, and then figure out how to have the system run the latest version by default... i don't recall if that included uninstalling older versions or not... sometimes older ones must be left on the system for other things that won't run with the newer...

Ok, apparently the official Oracle JRE is for Java 8. And they do not provide JREs for any versions after this. I grabbed a Java 21 JRE from here https://adoptium.net/temurin/releases/?os=windows&arch=x64&package=jre and it launches. Sorry for the confusion and thank you for the help. I guess if nothing else this issue might help point someone else in the right direction with Windows. It's strange to me that you have to go to a third party for a JRE, but now I know!

Oh dear. Sorry it seems I broke JDK8. It should be easy to "downgrade" it. I'll also test the initial start.
