luoyuxia commented on FLINK-30035:
----------------------------------

May similar issue to FLINK-30318, after FLINK-14055, we won't wrap therad's classload using Thread.currentThread().setContextClassLoader() with the added jars in SQL Client CLI, so if the any class in iceberg-flink-runtime-1.16-1.1.0.jar try to load the class using Thread.currentThread().setContextClassLoader(), it may well get an classload without all the added jars which is different from 1.15.

>          Components: Table SQL / Client
>    Affects Versions: 1.16.0

> I used to be able to run the sql-client with iceberg-flink-runtime jar using the `-j,--jar <JAR file>` option (e.g. with 1.15.2). 
> {code}
> ./bin/sql-client.sh embedded --jar iceberg-flink-runtime-1.16-1.1.0.jar
> {code}
> With 1.16.0, this doesn't work anymore. As a result, I am seeing ClassNotFoundException.
> {code}
> java.lang.ClassNotFoundException: org.apache.iceberg.hadoop.HadoopCatalog
> {code}
> I have to put the iceberg-flink-runtime-1.16-1.1.0.jar file inside the `flink/lib` directory to make the jar loaded. This seems like a regression of 1.16.0.
