Sample project demonstrating the issue

Hello,

I'm trying to compile an eclipse plug-in which contains java 7 compliant code.
I've added 
<plugin>
 <groupId>org.sonatype.tycho</groupId>
 <artifactId>maven-osgi-compiler-plugin</artifactId>
 <version>${tycho-version}</version>
 <configuration>
  <source>1.7</source>
  <target>1.7</target>
  <encoding>UTF-8</encoding>
 </configuration>
</plugin>
to the parent pom and 
"Bundle-RequiredExecutionEnvironment: JavaSE-1.7" 
in the manifest of the plug-in.

No matter if I remove one of those configurations or the other - the maven build still results in compilation failures though the project is built in eclipse with no errors.

I've made a sample project demonstrating the issue and attached it in an archive. 

If this could be a hint : 
If I run the build with Tycho version 0.9.0 the following line appear, though in the manifest java environment 1.7 is clearly stated.
"[WARNING] Overriding compiler source level 1.7 from POM with source level 1.6 from MANIFEST.MF"

If we'd like to adopt java 7 in our OSGI development but this issue needs to be solved. Please help!

Best Regards,
Dimitar
