Concatenative language interpreter in Java

Question

I'm interested in finding a concatenative language interpreter in Java. Ideally, it should satisfy the following conditions:

• It has an interpreter, not (only) a bytecode compiler for JVM.
• The language itself has decent documentation, not only a few examples and a "I'll document the rest someday" notice.
• The project is not completely abandoned.

In short, I'm looking for a reasonably "alive" concatenative language that can be embedded into Java easily.

7th is developed as a java script engine named "7th". There are examples how to interact between 7th and the calling Java™ program. Write Engine engine = Engine.create(); in Your Java program. Execute Your 7th program by sending it to the engine in the way: engine.eval(˂Your 7th program here˃).
