Plugin crashes with NPE at fields with final static (fixed value) #37

I have intially reported an issue with the jaxb2-fixed-value plugin to supported fixed values on attributes: https://github.com/fbdo/jaxb2-fixed-value/issues/1. The author adised to use <jxb:globalBindings fixedAttributeAsConstantProperty="true" /> as described in his IT. Unfortunately, that binding change makes this plugin crash:

[INFO] --- maven-jaxb2-plugin:0.10.0:generate (generate-model) @ helper-ws-model --- [INFO] Sources are not up-to-date, XJC will be executed. java.lang.NullPointerException at com.sun.tools.xjc.addon.krasa.Utils.getField(Utils.java:62) at com.sun.tools.xjc.addon.krasa.JaxbValidationsPlugins.hasAnnotation(JaxbValidationsPlugins.java:466) at com.sun.tools.xjc.addon.krasa.JaxbValidationsPlugins.processType(JaxbValidationsPlugins.java:252) at com.sun.tools.xjc.addon.krasa.JaxbValidationsPlugins.processAttribute(JaxbValidationsPlugins.java:455) at com.sun.tools.xjc.addon.krasa.JaxbValidationsPlugins.run(JaxbValidationsPlugins.java:154) at com.sun.tools.xjc.model.Model.generateCode(Model.java:294) at org.jvnet.mjiip.v_2_2.XJC22Mojo.generateCode(XJC22Mojo.java:66) at org.jvnet.mjiip.v_2_2.XJC22Mojo.doExecute(XJC22Mojo.java:41) at org.jvnet.mjiip.v_2_2.XJC22Mojo.doExecute(XJC22Mojo.java:28) at org.jvnet.jaxb2.maven2.RawXJC2Mojo.doExecute(RawXJC2Mojo.java:326) at org.jvnet.jaxb2.maven2.RawXJC2Mojo.execute(RawXJC2Mojo.java:168) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:132) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:208) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:153) at org.apache.maven.lifecycle.internal.MojoExecutor.execute(MojoExecutor.java:145) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:116) at org.apache.maven.lifecycle.internal.LifecycleModuleBuilder.buildProject(LifecycleModuleBuilder.java:80) at org.apache.maven.lifecycle.internal.builder.singlethreaded.SingleThreadedBuilder.build(SingleThreadedBuilder.java:51) at org.apache.maven.lifecycle.internal.LifecycleStarter.execute(LifecycleStarter.java:120) at org.apache.maven.DefaultMaven.doExecute(DefaultMaven.java:347) at org.apache.maven.DefaultMaven.execute(DefaultMaven.java:154) at org.apache.maven.cli.MavenCli.execute(MavenCli.java:584) at org.apache.maven.cli.MavenCli.doMain(MavenCli.java:213) at org.apache.maven.cli.MavenCli.main(MavenCli.java:157) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.plexus.classworlds.launcher.Launcher.launchEnhanced(Launcher.java:289) at org.codehaus.plexus.classworlds.launcher.Launcher.launch(Launcher.java:229) at org.codehaus.plexus.classworlds.launcher.Launcher.mainWithExitCode(Launcher.java:415) at org.codehaus.plexus.classworlds.launcher.Launcher.main(Launcher.java:356) [INFO]

That probably needs some special attention.

Tested with 1.3.
