Log4j.properties doesn't turn off output

I have a Java project ami

that has a dependency on my package pdf2svg

that has a dependency on Apache PDFBox 1.8.7

. PDFBox

outputs a lot of debug information from (for example org.apache.pdfbox.pdmodel.font.PDSimpleFont

) that I want to disable.

732 [main] DEBUG org.xmlcml.pdf2svg.PDFPage2SVGConverter  - startStream
2243 [main] DEBUG org.apache.pdfbox.pdmodel.font.PDSimpleFont  - Debug: 'WinAnsiEncoding' isn't a predefined map, most likely it embedded in the pdf itself.
2246 [main] DEBUG org.apache.pdfbox.pdmodel.font.PDSimpleFont  - Debug: 'WinAnsiEncoding' isn't a predefined map, most likely it embedded in the pdf itself.

      

        
        
        
      

    

PDFBox cannot be edited and I want to disable DEBUG. I have src/main/resources/log4j.properties

files in pdf2svg

and ami

which currently contain the following

log4j.rootLogger=DEBUG, A1

some commands seem to work, but others like

log4j.logger.org.apache.pdfbox.pdmodel.font.PDSimpleFont=ERROR

do not disable the output. Does it matter where I put the log4j.properties file? Is there an obvious answer to this problem?
