jython 2.5 can't print string

Question

Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_20
Type "help", "copyright", "credits" or "license" for more information.
>>> print 3
3
>>> print "3"
...

I tried version Jython 2.2.1, it was ok, but the problem remains in version Jython 2.7b1:

Jython 2.7b1 (default:ac42d59644e9, Feb 9 2013, 15:24:52)
[Java HotSpot(TM) Client VM (Sun Microsystems Inc.)] on java1.6.0_39
Type "help", "copyright", "credits" or "license" for more information.
>>> print 'ab'
...

are you sure you haven't typed `print '3"` or `print "3'` (mismatched quotes)? — jfs, Dec 10 '12 at 09:07

I tried this and my version works good:

Jython 2.5.3 (2.5:c56500f08d34+, Aug 13 2012, 14:48:36)
[Java HotSpot(TM) Client VM (Oracle Corporation)] on java1.7.0_09
Type "help", "copyright", "credits" or "license" for more information.
>>> print 3
3
>>> print "3"
3

I use more recent versions of both Jython and Java, but I think this is not problem in your case. Try to save those print statements in print_test.py file and execute it via jython print_test.py and with CPython python print_test.py. Show us results.

same problem here:

Jython 2.5.2 (Release_2_5_2:7206, Mar 2 2011, 23:12:06)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_02
Type "help", "copyright", "credits" or "license" for more information.
>>> print 'hi'
...

Looks like just a bug for 2.5.2

Perhaps this is specific to the OS or machine environment, as it behaves for me on windows in 2.7.0 and have seen it behave in previous versions.

Jython 2.7.0 (default:9987c746f838, Apr 29 2015, 02:25:11)
[Java HotSpot(TM) 64-Bit Server VM (Oracle Corporation)] on java1.7.0_51
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.platform()
'Java-1.7.0_51-Java_HotSpot-TM-_64-Bit_Server_VM,_24.51-b03,_Oracle_Corporation-on-Windows_7-6.1-amd64'
>>> print 3
3
>>> print '3'
3
>>> print "3"
3

What is the underlying OS and how are you invoking the console? Do you have the problem with constructs other than print or when not referencing a quoted string?
