这是个低级错误，本意是在获取异常对象时，假如当前线程不是抛出异常的线程则尽可能重新new一个，但是判断语句混入了.....：

        if (false && e.thrower != Thread.currentThread().getId()) {            Class<? extends Throwable> ec = ex.getClass();            try {                Constructor<?> noArgCtor = null;                Constructor<?>[] cs = ec.getConstructors();// public ctors only                for (int i = 0; i < cs.length; ++i) {                    Constructor<?> c = cs[i];                    Class<?>[] ps = c.getParameterTypes();                    if (ps.length == 0)                        noArgCtor = c;                    else if (ps.length == 1 && ps[0] == Throwable.class)                        return (Throwable)(c.newInstance(ex));                }                if (noArgCtor != null) {                    Throwable wx = (Throwable)(noArgCtor.newInstance());                    wx.initCause(ex);                    return wx;                }            } catch (Exception ignore) {            }        }
