> We've found JVMTI problem in DRLVM build (r472773 + HARMONY-2120 + HARMONY-2123) while running Java profiler tests. With this problem it's impossible to use Eclipse TPTP profiler for Harmony+DRLVM JRE.
> The problem is that even if JVMTI agent adds class search path for additional classes using AddToBootstrapClassLoaderSearch(), these classes are not found by DRLVM and result in ClassNotFoundException.
> For example, in the attached test Java application loads class located in a separate directory (extdir), which is not included into regular classpath. If the application is started without agent, it fails to lload this class and ClassNotFoundException is thrown. However, if application is started with agent and path to this separate directory is passed to the agent options, then agent uses AddToBootstrapClassLoaderSearch() to add this durectory to class searching path, and this class should be successfully loaded.
> Provided script run.bat demonstrates this by running application with agent and without agent. If you point to Sun or JRockit JRE, it will show expected result:
