Not at the moment. We'll keep the explicit clearing in place as long as we can. Once it is permanently blocked we'll probably have to rely on the fact that the Maps in question use a WeakReference and wait for GC to clear the references. That will make tracking down genuine memory leaks harder so we'll have to see if we can persuade the JRE team to provide some sort of replacement API if/when we reach that point.

RE: tomcat and sqlite
HI Mark,
I tried by creating a standalone application and to my surprise, there are no
.so and .so.lck files generated.
I used the same dependency and everything seems fine!
I am wondering what should I try now. Is it tomcat that is messing stuff for
me?
Any help is appreciated in this direction
Regards
Haseeb

Thanks. That de-registration code looks to be correct to me.
I suspect that this might require a change in the Driver. Some things to
test:
- can you delete the files if you shut Tomcat down first?
- how does the driver behave if you access it via a stand-along Java
application
I suggest you try and recreate this with a stand-alone Java app and if you
still see the problem. If you do, I'd suggest opening an issue against the
driver.
