I still experience issues with this and I’ve narrowed it down to the existence of a bindings file. If I remove the .xjb file then it works properly. However, when the .xjb file is present, the build fails with the java.security.PrivilegedActionException.

I still need the binding to convert XMLGregorianCalendar into a better type so prefer not to remove it. Does anyone have similar problem? Or a suggestion on how to solve it?

Try overriding the jaxb-runtime dependency inside maven-jaxb2-plugin.

	<build>
		<plugins>
			<plugin>
				<groupId>org.jvnet.jaxb2.maven2</groupId>
				<artifactId>maven-jaxb2-plugin</artifactId>
				<version>0.14.0</version>
				<dependencies>
					<dependency>
						<groupId>org.glassfish.jaxb</groupId>
						<artifactId>jaxb-runtime</artifactId>
						<version>2.3.3</version>
					</dependency>
				</dependencies>
				<executions>
                                ...

Overriding jaxb-runtime to anything >= 2.3.1 fixes this. (https://github.com/highsource/maven-jaxb2-plugin/issues/148)
