   > Still some questions in my mind,
   > 
   > 1. when it happens. As we does test it with Paimon extention, no test case 
failed. Any runtime combination for this?
   > 2. how it triggered. The only valuable information in the logs is the 
missing class `org/apache/spark/sql/connector/catalog/Column`, but it never 
used by `getOwner` method. What's the relation to the fix does this PR supposed?
   > 3. redundant ignoring exceptions in `getOwner`
   > 
   > I think proper investigation should come with,
   > 
   > 1. reproduce the error with the runtime combination on Spark 3.x specific 
version with Paimon extension
   > 2. investigate the real problem in parsing table or table owner
   > 3. fix them in place by distinguished Spark version, eg. <=3.2 and >=3.3, 
or etc.
   
   Kyuubi's paimon test use paimon 0.7.0, our case using paimon 0.9..0's spark 
3.2 extension jar.
