(1) Empty Instance Name:
TPTP uses JVMPI in before. JVMTI is used from Java 1.5. I also found the
problem you described. It needs to be investigated further. Maybe others
can give a help :)
(2) Percentage bar in Call Tree Tab
You can find the descriptions in Eclipse Help document about Call Tree:
"Monitoring and profiling applications > Monitoring and profiling
applications > Profiling an application > Profiling views > Using the
Execution Statistics view"
The percentage means the methods spend in a specific thread. But the
statistics seems strange because each thread instance shows 100%. I think
this is a defect.
(3) Objects allocation details info:
Please make sure memory anlysis option "Track object allocation sites"
(leve of detail) is checked before start profiling.
