I can't start schema registry and kafka rest. When I use kafka-rest-start then exception is occurred:
Exception in thread "main" java.lang.NoSuchFieldError: PASSWORD
nowhere can I find what that means.
EDIT
The exception:
Exception in thread "main" java.lang.NoSuchFieldError: PASSWORD

This may be a jar mismatch. I got this error but then when I updated the version of confluent-common installed as well, it went away.

We have upgraded the postgresql version from 9.6 to 13.8 in our lab. Post upgrade and initialization our application is keep restarting due to the below error in the log
Exception encountered during context initialization - cancelling refresh attempt: org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'migration': Unsatisfied dependency expressed through field 'dataSource'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'credentialedDataSource': Invocation of init method failed; nested exception is org.springframework.jdbc.CannotGetJdbcConnectionException: Could not get JDBC Connection; nested exception is org.apache.commons.dbcp.SQLNestedException: Cannot create PoolableConnectionFactory (The server does not support SSL.)
What does the above error mean? How to fix it? Do we need to do anything with the server.crt and server.key files? Meaning, reimport or regenerate.
Pls let me know if you need any other detail from me.
Just playing with the postgresql parameters in pg_hba.conf file
You need to carry the server.crt and server.key over from the old server to the new one (if you didn't already). You also need to change "ssl" parameter in the new postgresql.conf file, since you apparently haven't done so.
You should carefully consider the differences between the old postgresql.conf and the new one to decide how the differences should be resolved. 9.6 to 13 is a pretty big jump, and some parameters are new, some are obsolete, and some have changed their defaults or their meanings (or spellings).
A java.lang.NullPointerException exception has occurred.
However, the system should continue working without further problems.
When I create a class, I get this error.
Can you help me fix this error?
I'm using geoserver-2.20.3.war together with Apache Tomcat/9.0.36 on Linux. Everything works as it should but if i try to access the server status via the web administration interface i only get Error messages. I can't really figure out the problem and how to fix it.

I tried to find a similar issue but unfortunately did not stumble over something really helpful.
I found a solution! The problem were missing fonts. After following these very helpful steps by Andreas Ahlenstorf and installing the font-package dejavu-fonts on linux everything works fine.

There are jar files interdependent (though I took all latest was not compatible). Finally the combination worked is listed below.
solr-dataimporthandler-8.3.0.jar
solr-mongo-importer-1.0.0.jar
mongo-java-driver-2.13.2.jar
It was frustrating.

The stacktrace says: "the name apoc.algo.betweenness is already in use". So, perhaps you forgot to remove a previous APOC jar file from the plugins directory.
