Maven annotation processing fails with JDK9-ea+138

[Christian Beikov]

I am using the following plugin definition:

                     <plugin>
                         <groupId>org.bsc.maven</groupId>
<artifactId>maven-processor-plugin</artifactId>
                         <version>2.2.4</version>
                         <executions>
                             <execution>
                                 <id>process</id>
                                 <goals>
                                     <goal>process</goal>
                                 </goals>
<phase>generate-sources</phase>
                                 <configuration>
<compilerArguments>-J--add-modules=java.xml.bind</compilerArguments>
                                     <!-- source output directory -->
<outputDirectory>${project.build.directory}/test-metamodel</outputDirectory>
                                     <processors>
<processor>org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor</processor>
                                     </processors>
                                 </configuration>
                             </execution>
                         </executions>
                         <dependencies>
                             <!-- Metamodel -->
                             <dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-jpamodelgen</artifactId>
<version>1.3.0.Final</version>
                             </dependency>
                         </dependencies>
                     </plugin>

which invokes javac like this(according to the debug output)

[DEBUG] javac option: -cp
[DEBUG] javac option: ....
[DEBUG] javac option: -proc:only
[DEBUG] javac option: -J--add-modules=java.xml.bind
[DEBUG] javac option: -processor
[DEBUG] javac option: org.hibernate.jpamodelgen.JPAMetaModelEntityProcessor
[DEBUG] javac option: -d
[DEBUG] javac option: 
C:\Users\Christian\Documents\someproject\target\classes
[DEBUG] javac option: -s
[DEBUG] javac option: 
C:\Users\Christian\Documents\someproject\target\test-metamodel
