After several different trials, looks like I managed to solve this issue.

It all depends on the Java Development Kit used to make the AOSP build. I initially installed the Oracle JDK (as suggested by the android tutorial pages: http://source.android.com/source/initializing.html) but then I tried the Open-JDK, which is installed with:

sudo apt-get install openjdk-6-jdk

If you have both Open-JDK and Oracle-JDK installed, you can choose which one to use executing:

sudo update-alternatives --config java sudo update-alternatives --config javac sudo update-alternatives --config jar sudo update-alternatives --config javah sudo update-alternatives --config javadoc

and selecting the Open-JDK version for each of these.

The AOSP build using Oracle JDK failed to boot, while the one made with Open-JDK completed the boot just fine.

Hopefully it helps others to solve similar issues.

The build of the same sources worked fine when built in my Ubuntu 11.10 (64-bit) host. I did the migration like this:

1. full backup of the aosp source dir, from the 11.10 host
2. setup of a new Ubuntu 12.04 host
3. installation of AOSP pre-requisite packages
4. installation of Oracle jdk 6
5. restore of the aosp source dir (from 1)

The failure in "javax.net.ssl.KeyManagerFactory" suggests some SSL-related issue, but I wonder what I could be missing,...

Thanks in advance for any help.
