JVM TI is partially defined via xml that is processed at build time to
generate some of the sources. If you grep in your build directory you'll
fine eg:
./hotspot/variant-server/gensrc/jvmtifiles/*
You should be able to see how that redirects calls back to the sources
in ./share/prims/jvmtiEnv.cpp 9for example).
