Hi Daniel,

That's an interesting idea. I tried to build the compact JRE images with
'make images profiles' but I got this error:

## Starting profiles
make[2]: Entering directory '/home/ebourg/openjdk8/jdk/make'
make[3]: Entering directory '/home/ebourg/openjdk8/jdk/make'
make[3]: *** No rule to make target
needed by '/home/ebourg/openjdk8/build/images/libprofile_1/rt.jar'.  Stop.

debian/rules:968: recipe for target 'stamps/build' failed

Assuming this can be resolved there are some points open for discussion:

- How do we name the new packages? openjdk-8-jre-compact<n> would make

- Since these compact JREs do not provide the full Java API they can't
satisfy the java8-runtime and java8-runtime-headless virtual packages.
We'll have to introduce new virtual packages, I suggest
java8-runtime-compact<n>. As I understand the compact profiles do not
contain UI classes, so there is no need to have -headless variants here.

- What would be the install directory for the compact JREs? Currently
the full JRE/JDK is installed in /usr/lib/jvm/java-8-openjdk-<arch>. The
compact JREs could go into /usr/lib/jvm/java-8-openjdk-compact<n>-<arch>.
