Announcing Applino 1.0 (open source)

Most Java developers realise that it is inefficient to instantiate a
separate JVM for each Java application running on a user's computer.
This
involves a significant extra start-up time and is wasteful of memory.
Unfortunately, due to the need to segregate the effects of one
application
from another there hasn't been any choice.

On the server side however, much progress has been made in the area of
Java
Application Servers which are able to run multiple web applications
within
the same JVM. The level of intra application protection is so good
that
several hosting companies provide shared hosting where users host
their web
applications in the same JVM as other users.

The idea behind this project is simple: take the compartmentalisation
technology which has been developed for servlets and reapply it to
the
desktop space. This has proven to be exceedingly simple as concepts
such as
context life cycles and hierarchical class loaders map perfectly to
the
requirements of a mono JVM desktop environment.
