Currently the code, when it goes into exception, after printing "My message", also prints the stack trace. At any rate, ideally I can simply log a 1-line exception message and not the kitchen sink.

Pop out the top value as long as the stack is not empty and the price of st. to p is lower than or equal to the price of the current day. I found this SO answer, but in my application it looks like the container (Play framework on Netty) gets into the mix and logs its own 30 line stack trace to the log (30 lines is better than 100, but still 29 too many), Similarly, I found this thread in regard to Java 7 and the new option to suppress stack trace; however, for some reason, despite being on Java 1.7, with Eclipse configured for Java 1.7, only the old 2 param method of Throwable is available (and I do see the 4 param method when I click through to the Throwable class; maybe a Scala 2.9.2 library issue?). Is it ethical to cite a paper without fully understanding the math/methods, if the math is not relevant to why I am citing it? Andrew Grant's answer does not help getting a stack trace of the throwing function, at least not with GCC, because a throw statement does not save the current stack trace on its own, and the catch handler won't have access to the stack trace at that point any more. And, we will use try and catch blocks. When going through coding examples, it's quite common to have doubts and errors.
