wolfstudy opened a new issue #5465: [Pulsar Functions] User class constructor 
throws exception
URL: https://github.com/apache/pulsar/issues/5465
 
 
   **Describe the bug**
   
   A few days ago, I could use this command to create a function instance 
correctly, 
   ```
   ./bin/pulsar-admin functions create --retain-ordering --jar 
/Downloads/pulsar-util-function-api-pack-0.10.2-all.jar --classname 
ru.alfabank.api.utils.JournalBatchParseFunction --output-serde-classname 
ru.alfabank.api.utils.JournalBatchSerde --inputs test-input-topic --output 
test-output-topic --name test-serde-name
   ```
   
   but now I re-use the same command, the creation fails, the error is as 
follows:
   
   ```
