--------------------------------------------
{quote}hi！Is there any error that occurs when I execute
COSName.clearResources() when using PDFBox to convert an image or add a
watermark? When is it safe to execute COSName.clearResources()?{quote}
That method is what you are looking for. You may want to call
{{COSName.clearResources()}} from time to time to clear the cache as the
exactly as the javadoc proposes for long running environment. The underlying
map is synchonized so that you should not call the method to often to avoid
dead locks
> org.apache.pdfbox.cos.COSName#nameMap There is a memory leak problem.
