java util FileHandler INFO/DEBUG logs printing as STDERR

[RajeshMalla]

We have implemented simple spring boot application with java.util.logging, when we start application with docker run -p 8080:8080 -t springio/gs-spring-boot-docker
everything showing as "stdout", where as if we remove option "-t" and re-run then it is able to print "System.err.println" as STDERR and remaining all are in stdout.

I understand this might be process to create issue, or this may be related to forums. but still want to know answer. Can anybody help us how to instruct docker to distinguish b/w stdout and stderr ?
