- Replaced System.currentTimeMillis() by System.nanoTime() for timing tasks. 

- Changed the way how JAXBElements are created due to particularities with the creation of the XML Reference elements for the CertificateInstallationRes and CertificateUpdateRes messages. The JAXBContext is now set exactly for the message or field that is to be marshaled into XML. As a result, the JAXBContext is no more set in the EXI codec, but in the MessageHandler
- SecurityUtils.java has been partly rewritten with regards to the verification of certificate chains. See also verifyCertificateChain(…) method.
- Requirement [V2G2-812] is not implemented.
- When the EVCC sends a message out of the correct order which would induce a FAILED_SequenceError message, the SECC now sends the response message corresponding to the request message sent by the EVCC instead of the response message corresponding to the message the SECC would expect. As a result, ServerState.java has partly been rewritten and all SECC states have been adapted to it.
- Charge parameter provided by ChargeParameterDisoveryReq message are now thoroughly checked by the SECC. See also verifyChargeParameter(…) method.
- Charging profile provided by PowerDeliveryReq message is now thoroughly checked by SECC. See also isChargingProfileValid(…) method.
- New enum class PKI is added to shared.enumerations package. Needed for certificate chain checks in SecurityUtils.java.
- Some bugfixes in V2GTPMessage so that headers are not checked correctly.
