1、Keep the original commonNameMap.
2、When cleaning, you can use the ReferenceQueue to obtain the gc object and
delete the key, such as the java.util.WeakHashMap#expungeStaleEntries method of
weakhashmap, which can reduce a lot of invalid traversals.
You can try this to see if you can get support from the maintainers.
I personally think that to really solve this problem, we can only cache the
COSName of the current PDF scene instead of storing other PDFs, although this
change is relatively large.
