A Strange CFPDF issue in CF11

When we trying extract the content from PDF containing images getting strange error in the CF11 for cfpdf tag. But its working fine for PDF with out images (i.e. plain PDF with only content)

But both are working good in CF9.

Sample Code :

<cftry>

     <cfpdf action = "extracttext" source = "sample.pdf" destination="sample.doc" overwrite="yes">

     <cfdocument

              format="pdf"  srcfile="sample.doc" filename="sample1.pdf" overwrite="yes">

      </cfdocument>

     <cfcatch type="any">

            <cfoutput>Error Occured : #cfcatch#</cfoutput>

     </cfcatch>

</cftry>

Sample code is working fine in ColdFusion 9 for PDF containing images and with out images. But below error occurred when we try to extract the content from PDF conatining images

Error Occured : java.lang.IllegalArgumentException: Invalid bfchar pattern in ToUnicodeCmap

Thanks a lot in adavance
