All gc/lock/ tests do approximately the same thing. They verify that GC
|
|
is appropriately synchronized with certain class of functions.
|
|
|
|
- gc/lock/jni - uses JNI GetPrimitiveArrayCritical and GetStringCritical
|
|
- gc/lock/jniref - uses JNI NewGlobalRef, NewLocalRef, NewWeakGlobalRef
|
|
- gc/lock/malloc - uses malloc()
|
|
- gc/lock/jvmti - uses JVMTI Allocate
|
|

|
A number of threads is started. There are some threads that repeatedly
|
|
enter a critical section of code where functions describe above are
|
|
repeatedly called in a loop. There are also some threads that eat
|
|
memory in a loop. The idea here is to force GC to crash or deadlock.
