At this moment, tests for SAML adapters started failing during the release testing. In RH-SSO 7.5.2, the EAP version is set up to `7.4.3.GA-redhat-00002`. When the version is downgraded to `7.4.2.GA-redhat-00002`, everything works as expected. I've been trying to investigate the differences between those versions, but I haven't found anything related to that yet.

Pipeline run: https://keycloak-jenkins.com/job/universal-test-pipeline-adapters/925/

The major part of those failures occurs in `SAMLServletAdapterTest` due to the presence wide range of test matrices for the test. The cause of the failure is different expected length of the digital signature.

Dumped digital signature and its length.
With `JBoss EAP 7.4.3.GA-redhat-00002`:

With `JBoss EAP 7.4.2.GA-redhat-00002` (ignore the third row):
