Java version for QoRTs?

ytakemon commented 6 years ago

Hi @hartleys , I am trying to figure if I am running into a java version - QoRTs incompatibility here or if its an issue with my java environment in general (I typically do not work in Java so please forgive my ignorance here). I have the following java version and ran the command below:

[ytakemon@cadillac QoRT_install]$ java -version
java version "1.6.0_41"
Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode)

[ytakemon@cadillac QoRT_install]$ java -jar QoRTs.jar --help

And I am getting an error regarding major.minor version support.

Exception in thread "main" java.lang.UnsupportedClassVersionError: runner/runner : Unsupported major.minor version 52.0
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: runner.runner. Program will exit.

Any advice is appretiated. Cheers, Yuka

Right. QoRTs requires java v1.8 or higher.

Sorry about that.

Thank you @hartleys ,

I tried java build 1.8.0_20-b26, which didn' work. However, java build 1.8.0_73-b02 did work.

Cheers,
