如何识别具有特定数据的throwable(How to identify a throwable with specific data)

 我抓住了这个捕获任何未捕获的异常 
 
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread t, Throwable e) {
   }
});
 
 在方法内部，我想以不同于其他异常的方式处理以下异常： 
 
Caused by: java.lang.NullPointerException
    at com.company.si.stats.Statistics.hashString(Statistics.java:192)
    at com.company.si.stats.Statistics.sendStatistics(Statistics.java:127)
 
 我想基本上检查它是来自com.company.si.stats.Statistics.hashString nullpointer异常 
 
 我怎样才能做到这一点？ 我不确定我应该比较一下throwable中的哪些参数？ 
 
 抛出异常的代码不是我写的，所以我无法改变它。 
 
 重要说明我知道我接近这个问题的方式不正确。 但我无法访问提高异常的库，我需要一个解决方法，直到在库中修复了错误。 选择答案是因为它满足了我的需要，而不是通常应该是什么 

I have this caught that catches any uncaught exception
 
Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
            @Override
            public void uncaughtException(Thread t, Throwable e) {
   }
});
 
Inside the method, I want to deal with following exception differently than other exceptions:
 
Caused by: java.lang.NullPointerException
    at com.company.si.stats.Statistics.hashString(Statistics.java:192)
    at com.company.si.stats.Statistics.sendStatistics(Statistics.java:127)
 
I want basically to check that it is nullpointer exception coming from com.company.si.stats.Statistics.hashString
 
How can I do that? I am not sure what parameters in throwable I should compare against? 
 
The code where exception is thrown was not written by me, so I cannot change anything about it.
 
Important NOTE I know the way I am approaching this problem is not the right way. But I dont have access to the library raising the exception and I needed a workaround till the bug is fixed in the library. The answer was chosen because it satisfies what I need to, and not what generally should be dne
