VStar currently requires at least version 1.7 of Java.
As I've done a couple of times since 2010, I'm considering moving the minimum requirement up to Java 1.8, usually just referred to as Java 8.
If you think you are unable to run Java 8 on your computer, can you let me know please, either here or via my AAVSO contact page or email? This is only likely on quite old OS versions.
Here's the Java 8 download page with information about supported platforms (every OS, basically):
It's worth noting that Java 8 was first released in 2014 and updates for Java 1.7 ended in 2015.
I don't have a timeline for when a move to Java 8 will happen but I want to start thinking about it, exploring potential benefits and problems etc.
I can say more about the reasons for the desire to move to Java 8 if anyone is interested, but they fall into 3 main categories: performance improvements, language features, library enhancements/additions.
ps - I'm aware that many of you may already be running VStar with Java 8, perhaps without actually realising it. I am. What I want is to be able to make use of features present in Java 8 but not in Java 1.7 (or just Java 7) or earlier.
