Hi @wing328, @etherealjoy,

Would it be possible to have this PR integrated in a 7.5.1 release?
Because without that, the 7.5.0 release is not usable through Nexus IQ Server or Artifactory due to security scanner leveraging this critical CVE.

Regards.

[wing328]

thanks for the PR.

can you please fix the build failure when you've time?

we should be able to release v7.6.0 this week accordingly to the schedule

Hi @wing328,

Thanks for the fast reply.
About CI failure, this seems not related to my change.
I have closed and reopened this PR and the CI seems good now.

Regards.

[wing328]

does it build for you locally with mvn clean install?

[EstebanDugueperoux2]

Hum indeed from release 7.6.1 of TestNG a deprecated method has been removed (https://github.com/testng-team/testng/pull/2762/files).
It should be ok now.
