Is solace 10.11 compatible with log4j2 (v2.15)?

Hi there.

Because of the actual log4j issue (Log4j2 Vulnerability (CVE-2021-44228)), i was asked to change our jms client implemtation to use the latest version of log4j2 (v2.15). The previous log4j version used by the client was log4j-1.2.16. Everything was working fine there.

I know this old version is not affected, nevertheless i have to change it to 2.15. :-)
Since i changed the client implemenation, the client has failed with:

Exception in thread "Send-esb/t/kfl/test" java.lang.NoClassDefFoundError: org/apache/commons/logging/LogFactory
at com.solacesystems.jndi.SolJNDIInitialContextFactory.(
at java.base/java.lang.Class.forName0(Native Method)
at java.base/java.lang.Class.forName(

when connecting to our solace broker. We use solace client libs v10.11.
Did I miss something or is solace 10.11 not working with log4j2?

Thank you for your support.
Kind regards,
