CMS war not deploying

We are on Hippo CMS version 14.2.2
We updated log4j2 version to 2.15 but facing CMS war deployment issue on one of our instance after that.
The deployment worked fine locally, lower environments and one prod instance. But on one of the prod instances, CMS war deployment hangs with following message in the logs -
INFO [main] org.apache.catalina.core.ApplicationContext.log Initializing Spring root WebApplicationContext
INFO [main] org.apache.catalina.core.ApplicationContext.log No Spring WebApplicationInitializer types detected on classpath
Any pointers will be appreciated.
Thanks

Hi,

I highly recommend you upgrade to the latest version which is 14.7.2. The log4j 2.15 version is not sufficient to fix the issues in log4j and there are some problem with just updating the log4j version in the project. You will also benefit from other fixes and features added. Also, the version you are using is EOM so from a support standpoint we can only ask you to upgrade as your issue might already be fixed in the latest version.
