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 clonehttps://github.com/openjdk/jdk.git
cd jdk && bash configure && make jdk && cd ../
Does your JDK 18 build work in general? (EG: running 'java -version' or
compiling and running a simple HelloWorld.java program) If not, fix
that first.
git clonehttps://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
JDK 18 was advanced to classfile version 62 in this changeset:
https://github.com/openjdk/jdk/commit/b018c450e5e4737ccd08ed505fd06cee16c42648
This is a good question for the jcov-dev list at:
https://mail.openjdk.java.net/mailman/listinfo/jcov-dev
Please subscribe to jcov-dev before sending to the list.
See also this jcov bug report:

I hope this helps-

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
