The JVMTI works by using agents that communicate with the running JVM. These agents must be loaded at JVM startup and are usually specified via one of the command-line options {{â����‚�š�����‚�š����‚��“agentlibâ�����€š�š������€š�š�����€š���€œagentlib:}} or {{â����‚�š�����‚�š����‚��“agentpathâ�����€š�š������€š�š�����€š���€œagentpath:}}. However, agents can be specified in environment variables, although this feature can be disabled where security is a concern. The JVMTI is always enabled, and JVMTI agents may run under the default security manager without requiring any permissions to be granted.
