A DESCRIPTION OF THE PROBLEM :
I'm getting errors in the text output of the application I'm profiling.

Multiple of :
Profiler Agent Warning: Invalid declaringClass obtained from jmethodID
Profiler Agent Warning: mId = 0x3530f88, *mId = 0
Profiler Agent Warning: dCl = 0x2795e98, *dCl = 57536

Soon afterward I get this message repeated frequently.
*** Profiler engine warning: class sun.reflect.GeneratedConstructorAccessor1 that should be instrumented is not loaded by target VM
*** Requested classloader: sun.reflect.DelegatingClassLoader@2bf59432, its class = class sun.reflect.DelegatingClassLoader, index = 63, hashcode = 737514546
*** Profiler engine warning: target VM cannot load class to instrument sun.reflect.GeneratedConstructorAccessor1
*** probably it has been unloaded recently

Afterwards, memory allocations totals in jvisualvm profiling do not contain some classes in my application and are off significantly (taking into account recording only every 10 allocations) compared to heap totals. According to online posts, this behavior was in the Netbeans profiler ~2007 and was the result of dynamically generated classes being garbage collected before they were profiled, causing the crash. However, I'm not using dynamic classes in any used class. (The GUI has a couple of dynamic listeners, but I'm running on the command line.) Also, at least one class not showing up in the profiler (one with a one memory leak I fixed) was a strictly normal class with no inner classes or other unusual class definition.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Lode the code, execute jvisualvm, change to record stack allocation, start profiling.

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
All used classes showing up in the jvisualvm trace. Total reported memory in the profile is 1/10 of reported heap used. No error reports in the text output of the application.
ACTUAL -
Some classes are missing from the jvisualvm profiling and the memory used by these classes is not reported.

ERROR MESSAGES/STACK TRACES THAT OCCUR :
Profiler Agent: JNI On Load Initializing...
Profiler Agent: JNI OnLoad Initialized successfully
Profiler Agent: Waiting for connection on port 5140 (Protocol version: 10)
Profiler Agent: Established connection with the tool
