* DESCRIPTION
|
|
* The test performs a check whether JNI GetEnv function returns a valid JVMTI
|
|
* interface instance.
|
|
* The check consists of the following steps:
|
|
* 1) specific version (1.1) of the JVMTI interface is aquired
|
|
* 2) RetransformClasses event (introduced in 1.1) handler is enabled, so
|
|
* if the JVMTI interface doesn't support it, the test will fail
