Transition Graal to Java 8

[Deneau, Tom]

When I try mx eclipseformat -e /path/to/eclipse-4.4

I get a lot of messages like:
   The Eclipse formatter failed to format xxx.java. Skip the file.

Is this still supposed to work?

> 
> -vm
> /path/to/jdk1.8.0/bin/java

> 
> -vm
> /Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home/jre/lib/ser
> ver/libjvm.dylib
> 
> 
> 2. Ensure you are using an Eclipse that has 1.8 support. This is one of
> the following:
>  - Luna (4.4), version I20140318-0830 or later
>  - Kepler (4.3.2) with the patch at
> http://download.eclipse.org/eclipse/updates/4.3-P-builds installed.
>    Only select "Eclipse JDT (Java Development Tools) Patch with Java 8
> support (for Kepler SR2)" unless
>    you already have PDE installed.
> 3. Configure the JavaSE-1.7 and JavaSE-1.8 Execution Environments
> appropriately in Eclipse (Preferences -> Java -> Installed JREs ->
> Execution Environments) 4. If you want to build with ECJ, then download
> it[2] to mx/ecj.jar 5. Update mx/env so that JAVA_HOME points to the 1.8
> JDK and add a property EXTRA_JAVA_HOMES to point to a 1.7 JDK.
>    For example:
> 
> 
> JAVA_HOME=/Library/Java/JavaVirtualMachines/jdk1.8.0.jdk/Contents/Home
> 
> EXTRA_JAVA_HOMES=/Library/Java/JavaVirtualMachines/jdk1.7.0_51.jdk/Conte
> nts/Home
> 
> 6. Do a complete clean (just to be sure):
> 
> mx clean
> mx ideclean
> mx eclipseinit
> 
> 6. Remove and re-add all projects in Eclipse.

> Note that it is not yet quite open season on using Java 8 language
> features as Checkstyle does not yet support Java 8. In all likelihood we
> will replace Checkstyle with error-prone[3]. Either way, Checkstyle will
> be pulled out soon which removes the last road block to adopting all of
> Java 8.
