occur crash about dexposed HOT 4 OPEN

plz refer https://github.com/alibaba/dexposed/blob/master/dexposed/src/main/java/com/taobao/android/dexposed/DexposedBridge.java#L222
and
https://github.com/alibaba/dexposed/blob/master/dexposed/src/main/java/com/taobao/android/dexposed/DexposedBridge.java#L256
when before and after method occur exception，it should be catched!

and if the orignal method crash，it only try catch InvocationTargetException，（https://github.com/alibaba/dexposed/blob/master/dexposed/src/main/java/com/taobao/android/dexposed/DexposedBridge.java#L243）， so you should try catch your exception in your orignal method.

what i means is if the target method has try-catch blocked. will directly crash VM

example :

protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
String a = null;
try {
a.toString();
} catch (Exception e) {
e.printStackTrace();
}
Log.i("dexposed", "before");
}
as you can see,we already try-catch null point exception.but when VM try to fillStackTrace will lead VM directly crashed. make sense and any help ?
and the Crash log like this :

backtrace:
