Java 18 present but TWS installer script still downloads Java 1.8

 

I already have JDK 18 installed:
java -version
openjdk version "18" 2022-03-22
OpenJDK Runtime Environment (build 18+36-2087)
OpenJDK 64-Bit Server VM (build 18+36-2087, mixed mode, sharing

But running the TWS installer script doesn't use it and downloads 1.7 version. Why?

./tws-latest-linux-x64.sh?

if you check ~/Jts/tws, especially the test_jvm() function, you'll see that the java version is hardcoded there. i guess they only test tws against this version and hence they require exactly this version.
 

TWS is a Java application but, more importantly, it heavily depends on JavaFX, which is not part of the JDK any longer since Java 11.

JavaFX went through major changes and I suggest you simply let TWS use its own JVM with compatible JavxFX and JxBrowser. And Java 8 is designated a Long Term Support version with extended support until 2030.

Java 8 is still very widely used.?
