Hi All,

today I encountered (for the first time) a bug

the message

An exception has occurred in the compiler (1.8.0-ea). Please file a bug at
the Java Developer Connection (
after checking the Bug Parade for duplicates. Include your program and the
following diagnostic in your report.  Thank you.

suggests me to go to but this looks
like an official site (for official java versions up to version 7).

some more info about the bug (for those who are interested)

I try to implement some monad related stuff (from scratch).
I already successfully implemented code (not included in attachment) for
 o List
 o Option
 o Try (to deal with exceptions)
 o Stream (to deal with laziness)

Now I try to implement code (included in attachment) for
 o State

Implementing monadic binding (a.k.a flatMap) compiles fine.
Implementing monadic result (a.k.a. unit) produces a compiler error.

All comments are welcome.
