[ChandanKsingh12]

java.lang.ClassCastException: class org.hibernate.type.internal.BasicTypeImpl cannot be cast to class org.hibernate.type.BasicPluralType (org.hibernate.type.internal.BasicTypeImpl and org.hibernate.type.BasicPluralType are in unnamed module of loader io.quarkus.bootstrap.classloading.QuarkusClassLoader @163e4e87)

Please suggest me how to fix this issue.

This looks like a bug.

Assuming you can reproduce this on a supported version of Quarkus, please open a bug report with the requested information (Quarkus verison in particular) and above all include a reproducer: a small Quarkus project with just a few classes that are enough to trigger this error on startup. Without the reproducer, we're unlikely to be able to fix this.
