I see that the class of a lambda is isSynthetic() && !isLocalOrAnonymousClass(), but I presume that the same may be true for proxy classes.
Of course, I could check that getDeclaredMethods().length == 1 and apply regexp to the class name.
However I want to know if there is a more elegant and robust option to find out if a given object is a lambda.

The HTML 4 character entity references for the Greek capital and small letter lambda are Λ and λ respectively. The Unicode code points for lambda are U+039B and U+03BB.
The characteristics of lambda functions are: Lambda functions are syntactically restricted to return a single expression. You can use them as an anonymous function inside other functions. The lambda functions do not need a return statement, they always return a single expression.
Lambda is a compute service that lets you run code without provisioning or managing servers.
A lambda expression is a function or subroutine without a name that can be used wherever a delegate is valid. Lambda expressions can be functions or subroutines and can be single-line or multi-line. You can pass values from the current scope to a lambda expression. The RemoveHandler statement is an exception.
There is no official way to do this, by design. Lambdas are part of the language; and are integrated into the type system through functional interfaces. There should be no need to distinguish a Runnable that began life as a lambda, a named class, or an inner class -- they're all Runnables. If you think you have to "deal with lambda" by taking apart the class file, you're almost certainly doing something wrong!
