I can't reproduce the issue.

[Giesch]

I'm getting the same test failure.

[MathiasSM]

I have the same issue on Ubuntu 18.04.

$ java -version

@MathiasSM The Java LS build requires JDK 8:

java -version
java version "1.8.0_241"
Java(TM) SE Runtime Environment (build 1.8.0_241-b07)
Java HotSpot(TM) 64-Bit Server VM (build 25.241-b07, mixed mode)
$ javac -version
javac 1.8.0_241

[MathiasSM]

Didn't realize javac was not set to 8 🙃 thanks

[fbricon]

@snjeza we need to make jdt.ls not fail the build against JDK 11

[snjeza]

@fbricon could you create a new issue?

[snjeza]

Didn't realize javac was not set to 8 upside_down_face thanks
