Subject Isolates support
Date Tue, 10 May 2005 11:30:09 GMT
Hi everybody,

planning the development of a new virtual machine at this moment, it 
could be interesting to provide support for isolations.
I supose that most people will know the concept, but in short, the idea 
is to run several Java programs in parallel in one virtual machine (one 
OS process) and at the same time:
- keep all the Java programs in separate and effective sandboxes
- share the maximum resources (decompiled class code,etc)

For an indeep discusion of benefits and a running example you can look 
at http://research.sun.com/projects/barcelona/mvm/
There is also a JSR in process trying to determine a common basis for 
this kind of functionality: JSR-121. In any case, it is not necessary to 
comply to this JSR, because it is in some 'hold' state, but the ability 
to run isolates is a lower layer that can be implemented without any 
kind of JSR commitment.
