Integer can't be casted to Long for MySQL connector

[QAlanChan]

We're facing an issue about integer casted to long. Here are extracted error messages from the Airbyte Cloud log file:

Stack Trace: java.lang.ClassCastException: class java.lang.Integer cannot be cast to class java.lang.Long (java.lang.Integer and java.lang.Long are in module java.base of loader 'bootstrap')

If we follow the error message to investigate the 534th line of MySqlSourceJdbcPartitionFactory.kt file, it seems the same error can be easily reproduced by the following simple example.

fun main() {
    val value: Any = 123  // This is an Int (i.e. Java's java.lang.Integer)

    val longValue: Long = value as Long  // <-- This will throw ClassCastException
    println("Long value: $longValue")
}

Does anyone know about the issue or can anyone share your opinions?
Also, please let me know if you need whole log file to help with this topic.
