I'm being lazy here, but didn't find a quick answer via Google.
I have it in the back of my mind that the Java VM has some kind of
codepage sharing i.e. 2 java process running the same code on the same
machine will only use one memory space for the loaded class bytecode.
Each will have it's own data pages clearly.
1st question is - am I correct on this?
If this is true it leads to my 2nd question - whether Felix/OSGi
defeats? I'm assuming that any codepage sharing done by the VM would
be based on the absolute path to the JAR, and hence in an OSGi model
where we have a bundle cache per-process, the codepages may not end up
shared?
I thought they only memory mapped the JRE classes, not application
classes...
