Randomization of hashes of str/bytes, unicode/str and datetime objects is supported in newer CPython versions:
CPython >=2.6.8 in 2.6 branch
CPython >=2.7.3 in 2.7 branch
CPython >=3.1.5 in 3.1 branch
CPython >=3.2.3 in 3.2 branch
CPython >=3.3
-R option and PYTHONHASHSEED="random" environmental variable enable randomization of hashes in CPython <3.3.
Randomization of hashes is enabled by default in CPython >=3.3, so -R option and PYTHONHASHSEED="random" have no effect in CPython >=3.3.
PYTHONHASHSEED environmental variable can also be an integer in range [0, 4294967295], which sets predictable seed of hash values.
See: http://bugs.python.org/issue13703
I suggest that Jython 2.7 support -R option and PYTHONHASHSEED environmental variable.

Jython is highly unlikely to provide this feature -- we internally use ConcurrentHashMap from the JDK as our dict implementation and plan to keep it that way. Luckily the incredible Doug Lea is fixing ConcurrentHashMap for JDK8 and that will solve this problem for us. See http://concurrency.markmail.org/thread/tcv5cm762ouc47qa for details.
