首先,t.printStackTrace(pw); 获得stack trace字符串。这个t是 new Throwable()的结果。用户程序调用Log4J方法之后,Log4J自己又进行了4次调用,然后才获得了 t = new Throwable() : at org.apache.log4j.PatternLayout.format(PatternLayout.java:413) at org.apache.log4j.FileAppender.doAppend(FileAppender.java:...
Get Stack Trace With a Custom Function in JavaScript You can define a custom function that’ll produce a stack trace when an error occurs. Also, you have to place the function where an error occurs in your code. Meanwhile, the function works so that an error in your code causes an error...

13.9.printStackTrace,getStackTraceandgetMessage Recall fromSection 13.6that exceptions derive from classThrowable. ClassThrowableoffers aprintStackTracemethod that outputs to the standard error stream the stack trace (discussed inSection 13.3). Often, this is helpful in testing and debugging. ClassThrowable...
Unlike traditional Java profilers, async-profiler monitors non-Java threads (e.g., GC and JIT compiler threads) and shows native and kernel frames in stack traces. What can be profiled: CPU time Allocations in Java Heap Native memory allocations and leaks ...
