When an exception 3845N/A * is thrown which satisfies a currently enabled 3845N/A * {@link com.sun.jdi.request.ExceptionRequest exception request}, 3845N/A * an {@link EventSet event set} 3845N/A * containing an instance of this class will be added 3845N/A * If the exception is thrown from a non-native method, 3845N/A * the exception event is generated at the location where the 3845N/A * If the exception is thrown from a native method, the exception event 3845N/A * is generated at the first non-native location reached after the exception 3845N/A * Gets the thrown exception object. The exception object is 3845N/A * an instance of {@link java.lang.Throwable} or a subclass in the 3845N/A * @return an {@link ObjectReference} which mirrors the thrown object in 3845N/A * Gets the location where the exception will be caught. An exception 3845N/A * is considered to be caught if, at the point of the throw, the 3845N/A * current location is dynamically enclosed in a try statement that 3845N/A * handles the exception. (See the JVM specification for details). 3845N/A * If there is such a try statement, the catch location is the 3845N/A * first code index of the appropriate catch clause. 3845N/A * If there are native methods in the call stack at the time of the 3845N/A * exception, there are important restrictions to note about the 3845N/A * returned catch location. In such cases, 3845N/A * it is not possible to predict whether an exception will be handled 3845N/A * by some native method on the call stack. 3845N/A * Thus, it is possible that exceptions considered uncaught 3845N/A * here will, in fact, be handled by a native method and not cause 3845N/A * termination of the target VM. Furthermore, it cannot be assumed that the 3845N/A * catch location returned here will ever be reached by the throwing 3845N/A * a native frame between the current location and the catch location, 3845N/A * the exception might be handled and cleared in that native method 3845N/A * Note that the compiler can generate try-catch blocks in some cases 3845N/A * where they are not explicit in the source code; for example, 3845N/A * the code generated for <code>synchronized</code> and 3845N/A * <code>finally</code> blocks can contain implicit try-catch blocks. 3845N/A * If such an implicitly generated try-catch is 3845N/A * present on the call stack at the time of the throw, the exception 3845N/A * will be considered caught even though it appears to be uncaught from 3845N/A * examination of the source code. 3845N/A * @return the {@link Location} where the exception will be caught or null if 3845N/A * the exception is uncaught.
