Java 7 is End of Life'd since April: https://www.java.com/en/download/faq/java_7.xml so third party software built with an up-to-date Java won't work on Trusty (and Precise), which are still supported, without installing a PPA.
New releases (starting with 16.04 LTS) should default to OpenJDK 8, and it would be nice to backport OpenJDK 9 (http://openjdk.java.net/projects/jdk9/) as soon as possible to prevent this issue in a future (Java 8 EOL is estimated to be in September 2017 according to http://www.oracle.com/technetwork/java/eol-135779.html).
