TypeError: Cannot read property 'Id' of undefined

I got the following error while running jvm-mon. Not sure if there are logs I can inspect or not.

$ jvm-mon
TypeError: Cannot read property 'Id' of undefined
    at renderVmCharts (/usr/local/Cellar/jvm-mon/0.3/libexec/jvm-mon.js:174:25)

Hmm, appears to be this line:

jvm-mon/src/dist/jvm-mon.js

Lines 173 to 174 in 4d9a4fe

	function renderVmCharts(vm) {
	var vmHist = hist[vm.Id]

where 'vm' ends up undefined.

Does this happen on startup or after some action?

This does not happen with all my java programs. Anyway, it happens as soon as I try to inspect a java process.

I'm facing with this error too in centos.

Unfortunately, I'm not able to reproduce this issue.
Does it prevent you from monitoring all processes or just one?
