public final class SLReturnNode
extends SLStatementNode

Implementation of the SL return statement. We need to unwind an unknown number of interpreter frames that are between this SLReturnNode and the SLFunctionBodyNode of the method we are exiting. This is done by throwing an exception that is caught by the function body. The exception transports the return value.
