[collectd] JMX Plugin & Interval : Unable to parse string

[Greg]

    Hi collectd users,

I work with collectd on Debian Jessie for monitoring.
I have a problem with Java / JMX plugin.
As soon as I activate this plugin, I have an error in logs :
"cf_get_default_interval: Unable to parse string "300.000000" as 
number."

Where 300 is the Interval in collectd.conf.

If I suppress Interval, all work fine.

I tried with collectd v5.4.1 and v5.5.1 Debian packages. So I tried with 
collectd v5.5.1 source package and compile it : same problem.

I attach my config file.

This is the logs :
[2016-05-18 14:23:21] perl: Initializing Perl interpreter...
[2016-05-18 14:23:23] perl: Initializing Perl interpreter...
[2016-05-18 14:23:23] perl: Initializing Perl interpreter...
[2016-05-18 14:23:23] Initialization complete, entering read-loop.
[2016-05-18 14:23:23] cf_get_default_interval: Unable to parse string 
"300.000000" as number.



Thanks for help.
