Hello, I'm trying to compute code coverage for langtools in the JDK repo on a Ubuntu 18.04 machine using JDK 18 for the compilation. I have run the following commands:
``` cd /home/user git clone https://github.com/openjdk/jdk.git cd jdk && bash configure && make jdk && cd ../ git clone https://github.com/openjdk/jtreg.git cd jtreg bash make/build.sh --jdk /home/user/jdk/build/linux-x86_64-server-release/jdk/ cd ../jdk bash configure --with-jtreg=/home/user/jtreg/build/images/jtreg --with-jcov=/home/user/jtreg/build/deps/jcov/ make jcov-image ``` In the last command, I get errors with the following message: ``` Exception details: Unsupported class file major version 62 ... ``` and then the message: ``` SEVERE : wrong command for jlink mods: .... ``` I tried to compile JCOV with JDK 18 but without success. Does anyone know if it is possible to compute code coverage on the master branch? Kind regards, Stefanos Chaliasos
