Java 7 goes EOL some time after April 2015, around 7 months from the time of writing. It would make sense to migrate this deployment to a Java 8 base image well before then. I can't think of anything which should cause problems, but it's always better to find out sooner than later.
Both the java and dockerfile/java library images now support tags for Java 8. The former "official" image appears to be built on OpenJDK and the debian:experimental image while the latter is built on the Oracle JDK and the ubuntu:14.04 image. The dockerfile/java image is probably, therefore, preferable for most work.
