Repackaging Exceptions In Streams

Handling checked exceptions in Java stream pipelines is a common pain point since functional interfaces don't allow checked exceptions. Three approaches are explored: wrapping the checked exception in a RuntimeException (straightforward but loses type information), sneaky-throwing the exception using generics to fool the compiler (strongly discouraged as it hides undeclared exceptions), and a 'liftException' variant that declares the exception type while still sneaky-throwing (useful only when streams are never returned). Each approach aborts the pipeline on first error. The author recommends wrapping in a runtime exception if you must throw, and warns strongly against sneaky-throw patterns.
