All Linux distributions, all the BSD's (FreeBSD, OpenBSD, etc), etc.It is the opensourcing of IBM's Java runtime implementation called J9 which replaces Hotspot (the OpenJDK JVM). OpenJ9 This actually offers a different JVM (Java runtime) then OpenJDK does.Amazon Corretto Amazon's OpenJDK distribution.Or if you want the commercial support Oracle offers.įor completeness there are also other Java distributions you can use:
#JAVA RUNTIME ENVIRONMENT SOFTWARE#
This doesn't happen very often but there is some badly written Java software out there which does some dumb assumptions about the JRE it is running on. So why would you want to use Oracle's Java implementation? Well if you have software which only works with the original Java JRE. And the functionality is still there in OpenJDK, it's just provided by different implementations. This encompasses a very small amount of functionality. This was replaced with an opensource alternative in OpenJDK. For example the font rendering engine was such a component.

I say "mostly" because some parts of the Sun's Java couldn't be opensourced because Sun themselves licensed them from other parties. what is now Oracle JRE) as GPLv2 with classpath exception. OpenJDK is actually the name of the project when Sun opensourced their Java (ie. The Oracle JRE is mostly just a distribution of OpenJDK. I'm not a lawyer so what "commercial use" encompasses in the view of Oracle I'll leave to the lawyers.
#JAVA RUNTIME ENVIRONMENT LICENSE#
I understand this must all seem quite confusing.Īs of January 2019 you will need a license for commercial use of the Oracle JRE (what was known as the "original" Sun JRE) from Oracle. It basically uses the same sources as the Oracle JDK and is licensed as GPLv2 with classpath exception. TLDR Get your Java runtime from Adoptium (the new name of AdoptOpenJDK). The "Classpath" name is a reference to the GNU Classpath project.
#JAVA RUNTIME ENVIRONMENT CODE#
The effect is to mean that Java code that you write and then build / run using OpenJDK Java is NOT constrained to have any specific license. They could avoid this by switching to an OpenJDK-based release.ġ - The Classpath exception is amendment to the GPL that relaxes the GPL's restriction concerning (dynamic) linking with non-open code. If your customer is using a current Oracle release (including recent Java 8 releases) they will probably need to pay for Java SE Subscription. If your customer is using an OpenJDK-based release, they can use it without paying a fee.
#JAVA RUNTIME ENVIRONMENT UPGRADE#
(If they upgrade to a current release, it changes.) If your customer is using an old Oracle Java release (prior to April 16, 2019), they can continue to use without paying a fee. There is no fee for their use, and there are no limitations on what the software can be used for. These Java releases are covered by the GPLv2+classpath license. This includes the official OpenJDK binary releases, and any other releases built (by 3rd-parties) from the OpenJDK sources or a derivative. The FAQ elaborates on what "personal use" means.
#JAVA RUNTIME ENVIRONMENT FULL#
(The following text is taken from the Oracle Java SE Licensing FAQ.)įor full information and terms, refer to the OTN License Agreement for Java SE. Java 8 and older releases that were released prior to Apallow free use for any purposes.Īll releases since Aprequire a subscription be paid, unless your usage is are covered by the following exclusions. (I am not going to cover these, since it is most likely not relevant to the OP.) Some other proprietary Java releases may be subject to other (3rd-party) licenses.OpenJDK-based Java is subject to GPLv2 + "Classpath exception" 1.Oracle Java is subject to Oracle's proprietary licenses.Each one (in theory) can have different license terms. There are many different providers of Java.

However, there is no distinction between JRE and JDK in what the licenses permit.
