Hello,
Is there any way to get some sort of notification right *before* a fullGC happens so that some guys release their cache?
Is there something I can do for this? Thank you so much!
Below is a little background...
I noticed that the caching behavior of TTCFont is *still* relying on the old (and broken) behavior of weak references. Back then, when a WeakArray is in the old space and the referent is in the young space, the referent didn't get reclaimed until a fullGC. This behavior was quite nice; it releases the cache only when a big memory clean up is required. However, on recent VMs, the cache is released always go away because the reference from the weak array is the only reference to it.
Andreas already had a fix for it: http://impara.de/pipermail/tweak/2005-August/000881.html and I folded it to the eToys image (which should go into other images), and it seems to be working as expected. However, a little thing (which is not critical as his patch limits the upper limit of cache entries) is that the cache is kept even when a fullGC happens.
