fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * dtrace_jni.c defines all the native methods of the Java DTrace API. Every
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * native method is declared in a single class, LocalConsumer.java.
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * The data generating loop must explicitly release every object reference it
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * obtains in order to avoid a memory leak. A local JNI object reference is not
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * automatically released until control returns to java, which never happens as
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * long as the data generating loop runs. This applies to any JNI function that
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * obtains an object reference (such as CallObjectMethod() or NewObject()). A
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * local reference is released by calling DeleteLocalRef(), which is safe to
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * call with an exception pending.
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * It is important to check for an exception after calling java code from native
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * C, such as after notifying the java consumer of new data. Failure to do this
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * makes it possible for users of the interface to crash the JVM by throwing an
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * exception in java code.
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * Some JNI functions, like GetIntField() or ReleaseStringUTFChars(), do not
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * need to be checked for exceptions.
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * GetStringUTFChars() returns NULL if and only if an exception was thrown.
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * It is important to stop a DTrace consumer and remove it if an exception
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * occurs. This API guarantees that a consumer is stopped automatically if it
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * throws an exception. An application running multiple DTrace consumers
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * simultaneously should be able to continue running the others normally if any
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * Calls to libdtrace are not guaranteed to be MT-safe. Even if they are
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * currently MT-safe, they are not guaranteed to remain that way. To address
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * this, a global lock (the LocalConsumer.class reference) is used around calls
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * to libdtrace. In many cases, the locking is done in java, which should be
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * indicated in this file by a comment above the function that assumes prior
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * locking. To access the same global lock from native C code, the JNI function
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * MonitorEnter() is used. Each MonitorEnter() must have a matching
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * MonitorExit() or the application will hang (all consumer threads). The
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * consumer loop and the getAggregate() method require a per-consumer lock
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * rather than a global lock; in that case the argument to MonitorEnter() and
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * MonitorExit() is the consumerLock member of the LocalConsumer, not the
fb3fb4f3d76d55b64440afd0af72775dfad3bd1dtomee * LocalConsumer itself.

4ae67516a1d5dc4a5dbc761762bad5b596647388tomee * Changes to dtj_load_common() in dtj_util.c should not normally require a
4ae67516a1d5dc4a5dbc761762bad5b596647388tomee * version update, since dtj_util.c defines classes in the JDK, not classes in
