What causes this issue?

When you use exception classes in a method interface, they must be

this sorting rule, the compiler returns a syntax error. The background
to this is that a user of a method can recognize the sequence in which
it must catch the exceptions by the signature.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.
