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
...
Which version of jcov is this? I did a jcov test on my local build today
using what claims to be "3.0-9-jdk-asm+1.0" and it worked okay.
