You don't want to use finalize() it isn't guaranteed to be called and even if does get
called, it wrecks gc performance.
A real solution would be to do caller side analysis/weaving:
i.e.
POJOResource pr = new POJOResource;
pr.doSomething();
becomes (pseudo code)
POJOResource pr = POJOResourceManager.get();
try
{
pr.doSomething();
}
finally
{
POJOResourceManager.release(pr);
}
But this requires a fair bit of analysis of the bytecode.
A simpler solution would be to assume the resource has a close() method
and that it is called by the client. You would just identify the close operation
in the metadata.
The handles are just "proxies".
