[news.eclipse.tptp] Re: unknown classes and methods when profiling with

["Eugene Chan" <ewchan@xxxxxxxxxx>]

Hi Khilan,

Even tho you have specify your profiling session to collect all data, there 
are certain classes in the JRE being filtered out by default with the 
limitation of the profiler. Unknown methods may result with method defintion 
or method entry events being missed by the profiler before the profiler 
starts collecting.
