Cannot generate statistics for many properties:

[owolabileg]

Opening this after private discussions with @xiaohe27 and @yzhang90, so we can keep track.

When I tried to generate an agent that can produce monitoring statistics from all our agents, I got errors like this one:

============================
/home/owolabi/projects/rvtest/scripts/props/MultiSpec_1MonitorAspect.aj:1648
[error] The method getEventCounters() is undefined for the type S\
ortedMap_StandardConstructorsRawMonitor
System.err.println("#event - staticinit: " +
SortedMap_StandardConstructorsRawMonitor.getEventCounters().get("staticinit"));

                  ^^^^^^^^^^^^^
=============================

After private discussions, it seems that this only happens for raw monitors (about 90 properties), and the solution may be related to pull request 119 in RV-Monitor.

Repro Steps:

mop_dir="path-to-mop-files"
javamop -merge -s ${mop_dir}
mkdir -p ${mop_dir}/classes/mop
rv-monitor -merge -s -d ${mop_dir}/classes/mop/ ${mop_dir}/*.rvm -v
javac ${mop_dir}/classes/mop/*.java
rm ${mop_dir}/classes/mop/*.java
javamopagent ${mop_dir}/MultiSpec_1MonitorAspect.aj classes -n JavaMOPAgent -v

@owolabileg The problem should be related to the RV-Monitor's statistics function for raw monitors. It was addressed in RV-Monitor's issue 119 (private repo), but not merged to RV-Monitor's master branch, not mentioning the released version.
