Eric Yang commented on HDDS-1833:
---------------------------------

[~swagle] Sorry, I don't think that is true.  

>From [Java spec|https://docs.oracle.com/javase/specs/jls/se7/html/jls-15.html#jls-15.12.4]:

Example 15.12.4.1-2. Evaluation Order During Method Invocation

As part of an instance method invocation (ยง15.12), there is an expression that denotes the
object to be invoked. This expression appears to be fully evaluated before any part of any
argument expression to the method invocation is evaluated.{quote}

ExceptionUtils.getStackTrace() is fully evaluated before trace method invocation.
