Performance Test Report

jaxb2 (spring)

jaxb/v0

jaxb 2.3.1 (java)

jaxb/v1 , jaxb/v2 , jaxb/v3 :

• Using default package based javax api : org.lfenergy.compas.scl2007b4.model.SCL

jaxb 3.0.0 (java, jakarta)

jaxb/v4 , jaxb/v5 :

• Using custom package based jakarta api : com.github.jaxblib.xsd.jakarta.model.SCL

  instead of org.lfenergy.compas.scl2007b4.model.SCL

Test unmarshalling

• convert file to Java objects (SCL)
