Hi Dylan,

Your syntax looks correct. I gave it a try with a trivial class using
the Java 8 syntax:

    public class Foo {
        public Runnable r = () -> {};
    }

With javahelper/0.54 in unstable I got this:

    ebourg@icare:~$ jh_build --javacopts="-source 1.7" --no-javadoc
foo.jar .
    find . -name *.java -and -type f -print0 | xargs -s 512000 -0
/usr/lib/jvm/default-java/bin/javac -g -cp :debian/_jh_build.foo -d
debian/_jh_build.foo -source 1.7
    warning: [options] bootstrap class path not set in conjunction with
-source 1.7
    ./Foo.java:3: error: lambda expressions are not supported in -source 1.7
        public Runnable r = () -> {};
                               ^
      (use -source 8 or higher to enable lambda expressions)
    1 error
    1 warning


    ebourg@icare:~$ jh_build --javacopts="-source 1.8" --no-javadoc
foo.jar .
    find . -name *.java -and -type f -print0 | xargs -s 512000 -0
/usr/lib/jvm/default-java/bin/javac -g -cp :debian/_jh_build.foo -d
debian/_jh_build.foo -source 1.8
    /usr/lib/jvm/default-java/bin/jar cfm /home/ebourg/foo.jar
../_jh_manifest.foo Foo.class


So I fail to see what goes wrong with beagle.
