---------------------------------------
bq. This class <em>does not</em> provide the stack trace for security purposes.
Thanks [~zhenyi] for pointing that out. I totally missed that line while going
through that code yesterday.
Still thinking whether {{StringUtils#stringifyException}} is the right place to
fix.
{code:title=Throwable.java|borderStyle=solid}
public String toString() {
String s = getClass().getName();
String message = getLocalizedMessage();
return (message != null) ? (s + ": " + message) : s;
}
{code}
If we can call {{Throwable#toString()}} from
{{AuthorizationException#printStackTrace}}, then we will get class name and
message and not the whole stack trace.
Something like this:
{code:title=AuthorizationException.java|borderStyle=solid}
@Override
public void printStackTrace() {
printStackTrace(System.err);
}
@Override
public void printStackTrace(PrintStream s) {
// Do not provide the stack-trace
s.println(((Throwable)this));
}
@Override
public void printStackTrace(PrintWriter s) {
s.println(((Throwable)this));
}
{code}
[~xiaochen]: what do you think ?
