Fw: printStackTrace prints nothing

[lei.han@xxxxxxxxxxxxx]

I found a java bug report
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4966410
very similair like what I am experiencing.


It even has an example there which you
can run to test.

But I don't quite get the solution given
there. Does anyone know what "-XX:+FullSpeedJVMDI" and "-XX:-OmitStackTraceInFastThrow"
does? How would those options fix this problem?
Thanks!

Subject	printStackTrace prints nothing

My code has logic like

java.io.StringWriter writer = new java.io.StringWriter();
e.printStackTrace(new java.io.PrintWriter(writer));
String stackTraceString = writer.toString();

buf.append(stackTraceString);

LOG.error(buf);

But in my log file I only see

java.lang.NullPointerException

There is no stack trace after it and
also no print out like <<no stack trace available>>

How come the stack trace of java.lang.NullPointerException
has not been printed out?

Thanks!
