Love this feature! Thanks JBP team!

Now I have to try really hard to find something in the JBP to complain
about. :)

When deploying a Java application to Cloud Foundry the Java memory
settings for the application are decided based on the configured memory
weighting during staging. This means that, unlike other apps, if the
application is scaled to give it more memory it needs to be *restage*d it
to get updated Java memory settings. This has now been improved with an
improved memory calculator written by Steve Powell[2]. The Memory
Calculator[1] will be run during every application start to ensure the
application gets up-to-date memory settings, its output is shown during
staging.

(found in cache)
Memory Settings: -XX:MaxMetaspaceSize=64M -XX:MetaspaceSize=64M
-Xss995K -Xmx382293K -Xms382293K

Then scaling the application to double the memory will result in new
memory settings without having to restage the application.

cf scale my-application -m 1G

-Xmx768M -Xms768M -XX:MaxMetaspaceSize=104857K -XX:MetaspaceSize=104857K
-Xss1M


This new feature is currently available on the master branch of the
buildpack [3] and will be released in due course.
