Error messages in memoryusage plugin swallowed
----------------------------------------------

                 Key: FELIX-2952
                 URL: https://issues.apache.org/jira/browse/FELIX-2952
             Project: Felix
          Issue Type: Bug
          Components: Web Console
            Reporter: Konrad Windszus


Using Web Console 3.1.8 and Web Console Memory Usage Plugin 1.0.2 the result of 
the POST-Request after clicking "Dump Heap" is swallowed, because the page is 
automatically reloaded just after the pop-up dialog was shown. The timeframe is 
much too short to be able to read the message in the dialog. This is especially 
annoying in a case where the dialog says, something like: Failed dumping the 
heap, JVM does not provide known mechanism to create a Heap Dump. I can 
reproduce the behaviour with Chrome (11.0), Firefox (4.0.1). 

With IE7 I only get a Javascript error message when I load the Memory Usage 
plugin in the browser because of line 169:
var __overall__ = {'Verbose Memory Output':'yes','Pending Finalizable 
Objects':'0','Overall Heap Memory Usage':'init = 1610612736(1572864K) used = 
1705655200(1665678K) committed = 2147287040(2096960K) max = 
2147287040(2096960K)','Overall Non-Heap Memory Usage':'init = 
136773632(133568K) used = 421843952(411956K) committed = 671977472(656228K) max 
= 2197815296(2146304K)',};

IE does not like that after the last comma follows nothing.
