…rta.management.j2ee-api removal

- reverted some changes from the previous commit
- removed tests depending on the j2ee-api jar

…d deprecated Proxy.getProxyClass

- EJB tests failed on JDK17 because of this
- also more consistent generateAndLoad (to be finished in next commits)

- ejb_all/ejb_group_1/ejb_group_2/ejb_group_3/ejb_group_embedded
- added add-opens where required
- new group for embedded as it is significantly different than others
  and I often required to execute it separatedly
- added -Dorg.glassfish.gmbal.no.multipleUpperBoundsException=true for the
  standaloneclient test stub
- tests will fail, but with this commit it means that they do work!!!

- not completely as under some circumstances we cannot live without them
- but we can decide when
- if the class was generated in the same package, the usage and the classloader
  are suitable, we can use MethodHandles. Otherwise we have to use the
  ClassLoader.defineClass method (accessed by reflection)
- we had to avoid using Base class from PFL, because it uses just MethodHandles
  XOR ClassLoader XOR Unsafe depending on the JDK.
- this solution was tested by
  - glassfish's ejb_all tests with JDK11 and JDK17
  - TCK/ejb with JDK11

…ot in the same package

- that means that we cannot use the MethodHandles.Looku.defineClass impl

…execution's garbage

- formatting of the code to make it easier to read
- fixed several log messages (wrong formatting)
- ContainerInfo used to reduce duplications
- replaced several deprecated method calls with simple straight replacements
- deleted 20 years old TODOs

- memory and cpu settings tested for current hardware usually used on jenkins,
  respecting limits
- compilation without test with parallelized maven execution
- upgraded jnlp
- separate settings for maven and ant tests
- bundles content with fast compression, excluded what we don't need

Fixed ejb tests + Fixed generating EJB classes
