Pascal Schumacher commented on PDFBOX-5731:
-------------------------------------------
Would it not be better to keep initializing the ConcurrentHashMap with an
initial capacity as otherwise even the 569 common names will cause multiple
resizings of the map (default initial table size is only 16)?
> org.apache.pdfbox.cos.COSName#nameMap There is a memory leak problem.
