Asier Baranguán 4 Years Ago Hi Which JDK version are you using? For JDK8 the properties should be: -Dcom.sun.xml.internal.bind.v2.runtime.JAXBContextImpl.fastBoot=true -Dcom.sun.xml.internal.bind.v2.bytecode.ClassTailor.noOptimize=true It seems that those packages get refactored (note the added '.internal' package) Regards.
