getting rid of some warnings

[Zoltan Lippai]

Hi,

I'm running jsignpdf on my Ubuntu server in CLI mode. I get several warnings when I sign a PDF and I would like to solve those issues or just hide the warnings.

Sending the full output to /dev/null is not an option, because I still need to know if anything bad happens. This is my current output:

WARN  net.sf.jsignpdf.utils.PropertyProvider$ProperyProviderException: Property file /root/.JSignPdf doesn't exist.
log4j:WARN No appenders could be found for logger (net.sf.jsignpdf.ssl.SSLInitializer).
log4j:WARN Please initialize the log4j system properly.
log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by net.sf.jsignpdf.utils.KeyStoreUtils (file:/root/cron/jsignpdf/JSignPdf.jar) to field java.security.KeyStore.keyStoreSpi
WARNING: Please consider reporting this to the maintainers of net.sf.jsignpdf.utils.KeyStoreUtils
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

The first line I understand, but is there a way to not have that file and not get the warning either? I'm providing all the details on the command line.

The other ones I really have no idea how to hide.

Thanks,

Zoltan

Hi Rajendra,

Ubuntu version is:

zolcsi@aragorn:~$  lsb_release -a

No LSB modules are available.

Distributor ID: Ubuntu

Description: Ubuntu 18.04.1 LTS

Release: 18.04

Codename: bionic

zolcsi@aragorn:~$ uname -a

Linux aragorn 4.15.0-33-generic #36-Ubuntu SMP Wed Aug 15 16:00:05 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux

Tried to run it from a simple user account, but the results are the same.

This is the command that I use:

zolcsi@aragorn:~$ java -jar /home/zolcsi/jsignpdf/JSignPdf.jar \

Hi,

the first issue can be workarounded by creating an empty config file -
either in home directory:
touch ~/.JSignPdf

or in another directory (e.g. in JSignPdf installation dir) and
configuring custom user.home property in java:
touch /path/to/.JSignPdf
java -Duser.home=/path/to -jar JSignPdf.jar ...

The second problem is related to using a newer Java version (9+) which
comes with the module system and better package protection. To avoid
the warning add following --add-opens java argument:
java --add-opens java.base/java.security=ALL-UNNAMED -jar JSignPdf.jar ...

Regards,

One more thing, you should run the java command from the JSignPdf
installation directory:
cd /home/zolcsi/jsignpdf
java -jar JSignPdf.jar ...
