Modularity is an important aspect of large Java systems. Build scripts and projects are often split up into modules in order to improve the build, but this is rarely taken into account at runtime ...

Get primed on the shortcomings of traditional modular programming in Java and find out how Project Jigsaw, OSGi, and Penrose could end up working side by side in Java 9.

Java 9 could introduce modularity and new value types. Improved modularity could reduce app size and improve startup performance. New value types will make it easier to program arrays.

Beyond Java EE 6, modularity will be key, according to the Oracle officials. OSGi, meanwhile, plays an important part of the Java ecosystem and Java platform overall, Harris said.
