We don't usually have individual tests on the 'serviceability' level.
Please move test into 'attach' folder. It is test for fix in the attach
mechanism.

Wouldn't be easier to have single env variable like ATTACH_CMD `.../bin/jcmd
45678 JVMTI.agent_load some.jar` which is completely set by java? So native
code is simplified and there are less dependencies.
