The plugin now requires either the json or simplejson python library to work.
Python 2.6 or higher ships with json, in this case, the plugin will work justas before.
simplejson is available for Python 2.5 and higher, installation of this packageis required for the plugin to work.
Older python versions are not supported, please query your Jolokia instancesfrom another host in these cases (recommended) or continue to use the old versionof the plugin. (not recommended)
In absence of the json or simplejson python libraries, the mk_jolokia pluginwould previously try to parse the Jolokia response with python eval(), allowinga MITM attacker to inject arbitrary code.
