/**
 * Similar to {@link CalledByNative}, this also exposes JNI bindings to native code. The main
 * difference is this <b>will not</b> crash the browser process if the Java method throws an
 * exception. However, the C++ caller <b>must</b> handle and clear the exception before calling into
 * any other Java code, otherwise the next Java method call will crash (with the previous call's
 * exception, which leads to a very confusing debugging experience).
 *
 * <p>Usage of this annotation should be very rare; due to the complexity of correctly handling
 * exceptions in C++, prefer using {@link CalledByNative}.
