Oracle has decided to promote the release of Java 8 by scrolling to 2014. The company is forced because the developers had to free up the vulnerabilities in the existing versions of Java to fix it.
Oracle says this decision have been taken because a significant part of the development team is used to acute vulnerabilities in the existing versions of Java to fix it. Because of this there are temporarily not enough developers available to the original deadline of Java 8 to achieve. In addition, it tells Oracle that it does not want to cut in the trial period of Java 8, also the problem of new security holes in Java 6 and 7 to prevent. Also the dropping of Project Lambda would be undesirable, because the featurelijst very limited would be if this component is missing in Java 8.
