Re: [Jepp-users] Simple test which shows memory leak in Jepp.

Hi Matthew,
I am able to reproduce the leak using jepp2.4 compiled on redhat
enterprise 4 x86_64 with python2.5.1 and this java:
Java(TM) SE Runtime Environment (build 1.6.0_10-rc-b28)
Java HotSpot(TM) 64-Bit Server VM (build 11.0-b15, mixed mode)
I also see a problem using the windows version of jepp from the
sourceforge pages (jep-2.5-Java6-python25.exe). Java is up to date
(1.6.0_23) in this case. Full details are below.
If Mike is not seeing the leak, I'm wondering what we're doing wrong? It
took me a while to figure out how to run the unit test - I hope that
doesn't have an effect.
Cheers
Jon

Versions:
C:\Program Files (x86)\Jepp>"c:\Program Files
(x86)\Java\jre6\bin\java.exe" -cp jep.jar jep.Run console.py
No readline available.
You may want to set the LD_PRELOAD environment variable, see the
README file for details.
i.e.: export LD_PRELOAD=/usr/lib/libpython2.3.so.1.0
If your platform really doesn't have readline, try this:
http://newcenturycomputers.net/projects/readline.html
>>> import sys
>>> sys.executable
'c:\\Program Files (x86)\\Java\\jre6\\bin\\java.exe'
>>> sys.version
