com.google.gwt.core.shared.SerializableThrowable

A serializable copy of a {@link Throwable}, including its causes and stack trace. It overrides {@code #toString} to mimic original {@link Throwable#toString()} so that {@link #printStackTrace}will work as if it is coming from the original exception.

This class is especially useful for logging and testing as the emulated Throwable class does not serialize recursively and does not serialize the stack trace. This class, as an alternative, can be used to transfer the Throwable without losing any of these data, even if the underlying Throwable is not serializable.

Please note that, to get more useful stack traces from client side, this class needs to be used in conjunction with {@link com.google.gwt.core.server.StackTraceDeobfuscator}.

      SerializableThrowable throwable = SerializableThrowable.fromThrowable(new Exception());
      throwable.setDesignatedType(
          "com.google.gwt.junit.client.GWTTestCaseTest$SomeNonSerializableException", true);
