check_jmx plugin chokes on more than 2Gb memory

[Adam Serediuk]

Old message, but I had the same problem. check_jmx  was built using  
Integer's for numbers and the Java Integer type is not able to handle  
values larger than 2^31-1(2147483647.) When you pass a value larger  
than this NumberFormatException is thrown. I have no idea who the  
original author is, but the source code was with the bundle I  
downloaded so I've updated it to use a Long rather than an Integer and  
values up to 2^63-1 are now supported.

I have uploaded the patched version to NagiosExchange at http://www.nagiosexchange.org/cgi-bin/page.cgi?g=Detailed%2F3002.html;d=1

Hope it helps.
