Java run issue

[Gaut1993]

Hello,

I have an issue when I try to run mixcr for the first time, it appears to be related to java version :

Exception in thread "main" java.lang.UnsupportedClassVersionError: com/milaboratory/mixcr/cli/Main has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

Hi,
What Java version do you have?

[Gaut1993]

Hello I'm using :
java version "1.8.0_401"
Java(TM) SE Runtime Environment (build 1.8.0_401-b10)
Java HotSpot(TM) 64-Bit Server VM (build 25.401-b10, mixed mode)

MiXCR is not compatible with 1.8. I recommend updating to the latest version.
