Java difficult to compromise with each other and the future is clear

This reporter Liu Hongyu java The future of the uncertain situation seems to be due to the IBM release of a message changed. According to foreign media reported October 12, IBM will be related to Java development work from the Apache Harmony Project to OpenJDK. According to IBM's official statement, the move "eliminates some of the uncertainties surrounding Java's future development".　　However, such leeway is still not to allow developers to completely eliminate doubts. To be clear about what to worry about, you might want to start with some of the things that split Java. The common JDK for Developers (Java Development Suite) is the core of Java, but it does not mean that only the JDK developed by Sun (now incorporated into Oracle) is the only authentic, such as early Oracle, IBM, and the GNU Open source Kaffe, OPENJDK are authorized　　, they are also called JDK, and they are complementary in performance. But there is also a great reputation for the alternative, that is based on the Apache Protocol harmony, which, far from getting the early recognition of sun, and sun turned the face. An open letter was issued by the Apache Software Foundation executive on its official website in 2007, refusing to accept Sun-provided license terms for JCP. Unfortunately, until the acquisition, Sun also did not make an official response, I do not know it is disdain to do so, or have already been burned, for the moment tolerated the management of the "Leng tou kid."　　Interestingly, it was mentioned in the letter that the project was originally donated by IBM, and clearly the subtext was "don't get in with IBM". In support of Java, IBM has always stood firm with sun and benefited from it.　　Now that the situation has changed subtly, Sun's club has replaced Oracle, a club that tries to take full control of Java and let it hatch golden eggs as a role for the perpetrators. In comparison, Sun is hardware thinking, open source Java is the decision after the open source Solaris, the intention is to rapidly expand the Java application area, resulting in a knock-on effect, because the best matching depth optimization can attract customers to choose their SPARC server. In this sense, IBM is Sun's ally. Now, Oracle is a software mindset that values Java, which was not found to be a reasonable business model by Sun.　　IBM is at this time the full competition with Oracle rivals, a large number of applications Java has become IBM's Achilles heel, of course, Oracle will use the reserved Java control to curb IBM's business development. So why did Oracle start with Google? This is actually Xiangzhong, Etian. Google's Android system uses Java Syntax +java Core class Library +android class library +android virtual machine, it is with the help of Harmony,googleIt's possible to launch Android so soon. Just, Google hit the ball, let Sun eat grievances. But the most radical split in the Java camp is the harbinger of a multipolar Java lake, which, if left unchecked, is hard to argue about. Oracle can not allow others to challenge their position, and hold their jobs to make money.　　More importantly, tapping Google, with warning harmony and IBM behind it, also eliminates direct contact with IBM, which is much less costly than the cost of tearing the skin. From the news of IBM's announcement of the Java Project migration, Oracle's tricks worked, and IBM compromised. However, this kind of compromise does not have the means to change the permanent peace, the Java future will also face too many variables.
