* Each evaluation of the java macro sends an expression to the java process and receives a result expression. Since most of the results will stay constant throughout the lifetime of the session (as they refer to classes, fields and methods), they are cached and subsequent evaluation of the same (java ...) expression will refer to the cached value instead. You can disable this caching (in case you are doing rather funky things) with the help of the java-enable-cache form (see below).

* Java objects which are returned from the Java-side can be safely used and are only garbage collected when no more references exist.
