After Java 6 it took almost five years to create a new Java major release. In the meantime the original Java inventor Sun Microsystems have been acquired in 2010. Java 7 is the first release under new owner Oracle.
One of the reasons for the long delay of Java 7 was the long design and development
time for a lambda syntax for the Java language. While this feature was finally
dropped from Java 7 the required mechanics under the hood like INVOKEDYNAMIC
and method handles have been added to the Java runtime with this release.
