Class WrongMethodTypeException

java.lang.Object

java.lang.Throwable

java.lang.Exception

java.lang.RuntimeException

java.lang.invoke.WrongMethodTypeException

All Implemented Interfaces:: Serializable

public class WrongMethodTypeException extends RuntimeException

Thrown to indicate that code has attempted to call a method handle via the wrong method type. As with the bytecode representation of normal Java method calls, method handle calls are strongly typed to a specific type descriptor associated with a call site.

This exception may also be thrown when two method handles are composed, and the system detects that their types cannot be matched up correctly. This amounts to an early evaluation of the type mismatch, at method handle construction time, instead of when the mismatched method handle is called.

Since:

1.7
