How to enable aspectj compile time weaving with Java 7 and maven

Question

I have a project which currently works with java 6 and compile time weaving. We use the following pom to enable spring aspects and our own ones:

<plugin>
  <groupId>org.codehaus.mojo</groupId>
  <artifactId>aspectj-maven-plugin</artifactId>
  <version>1.4</version>
      <configuration>
        <showWeaveInfo>true</showWeaveInfo>
        <source>1.6</source>
        <target>1.6</target>
        <Xlint>ignore</Xlint>
        <complianceLevel>1.6</complianceLevel>
        <encoding>UTF-8</encoding>
        <verbose>false</verbose>
        <aspectLibraries>
          <aspectLibrary>
             <groupId>org.springframework</groupId>
             <artifactId>spring-aspects</artifactId>
          </aspectLibrary>
        </aspectLibraries>
      </configuration>
      <executions>
        <execution>
          <goals>
            <goal>compile</goal>
            <goal>test-compile</goal>
          </goals>
        </execution>
      </executions>
    </plugin>

I've tried various configuration but can't make it work with java 7. If someone could share a working pom or leads it would be great.

After moving to version 1.7.0 of the aspectjtools it works fine. In addition you need to pass the compiler the version parameter as -1.7 (using the target parameter caused problems). If someone needs more details leave a comment and I'll add more configuration specific information.
You can take a working example from here: Spring, AspectJ and Maven example
Here is the working plugin definition from the pom (compiler-version="1.7", aspectj.version="1.7.0")

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>aspectj-maven-plugin</artifactId>
    <version>1.4</version>
    <configuration>
        <showWeaveInfo>true</showWeaveInfo>
        <source>${compiler.version}</source>
        <target>${compiler.version}</target>
        <Xlint>ignore</Xlint>
        <complianceLevel>${compiler.version}</complianceLevel>
        <encoding>UTF-8</encoding>
        <verbose>false</verbose>
        <aspectLibraries>
            <aspectLibrary>
                <groupId>org.springframework</groupId>
