Running Birt 4.7 is throwing some warnings regarding on com.lowagie.text_2.1.7.v201004222200.jar

Here is the warning:
Quote:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.lowagie.text.pdf.MappedRandomAccessFile$1 (file:/Birt/lib/com.lowagie.text_2.1.7.v201004222200.jar) to method java.nio.DirectByteBuffer.cleaner()
WARNING: Please consider reporting this to the maintainers of com.lowagie.text.pdf.MappedRandomAccessFile$1
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release


I started researching about it. In Birt 4.8 that library remains. So I was wondering if in future versions of Birt runtime there will be an update to that library, or if it will be replaced in order to avoid this.
Soon or later this will be an exception and something needs to be done

Any idea about that?

That v2.1.7 of iText is very old and the last open source build as far as i know. More recent versions require licences so i don't think that it will be updated in BIRT any time soon.

Might consider swapping iText out in favor of Apache PDFBox?

But that's something Birt should do, right? I mean.. It is used inside birt runtime library.

Thank you for your reply

any idea?
