• 1 x signature tests
  PR to update signatures in TCK https://github.com/eclipse-ee4j/jakartaee-tck/pull/256
• 2 x faulty timeout tests https://github.com/eclipse-ee4j/jakartaee-tck/issues/260
  PR to fix the tests https://github.com/eclipse-ee4j/jakartaee-tck/pull/261

5 Tests 'fixed' by appropriate system property configuration (see above). No need for the server.xml changes.

• 4 x extensions (TCK assumes invalid extensions are ignored)

  Need to discuss expected behaviour if an unknown extension is specified. Are these required or optional?
• 1 x timeout related test expects more frequent expiration checks

Expected results (Java EE 8)
