In this issue, the editor will bring you about the difference between OpenJDK and OracleJDK. The article is rich in content and analyzes and narrates it from a professional point of view. I hope you can get something after reading this article.

1. Differences in authorization protocols: OpenJDK is released using GPL V2 protocol, while SUN JDK is released using JRL. Although both protocols are open source, the difference in use is that GPL V2 allows commercial use, while JRL only allows individual research.

2. OpenJDK does not include Deployment (deployment) functions: deployed features include: Browser Plugin, Java Web Start, and Java control panel, which can not be found in OpenJDK.

3, OpenJDK source code is not complete: this is easy to think of, in the OpenJDK using the GPL protocol, part of the source code of SUN JDK can not be opened to OpenJDK because of property rights, the most important part is the optional component SNMP part of the code in JMX.

4, part of the source code is replaced by open source code: due to the problem of property rights, a lot of property rights are not SUN source code is replaced with some open source code with the same function, such as font rasterization engine, using Free Type instead.

It is not published by the Free Software Foundation, nor is it a statutory distribution term for software using the GNU General Public license. ─ has such effect only in the English original version of the GNU General Public license.
