Oracle recently announced that Java JDK is now premium JDK and stop providing free support after launch JDK 11. You can use JDK 11 for production but can’t use for commercial use. So you’ve to do.

Today in this article, I am going to give some alternative of Premium JDK which gives you a headache-free programming. From the many mouths, you hear about Open JDK is an alternative of premium JDK. But in the market many of Open JDK available. So which one is better for you. Let’s find out.

List of Alternative of Premium JDK

Without further ado, check out the following JDKs that are ready to download:

1Oracle JDK

This is the main distributor of Java 11 (already released). This is a commercial version of the brand with paid support. It can be downloaded and used free of charge for development use only.

It cannot be used in production without paying Oracle (so it’s a trap for the unsuspecting). Oracle intends to provide full, paid support until 2026 or later. Note that, unlike the past, Oracle JDK is not “better” than the OpenJDK build (as long as both are at the same level as the security patch).

2OpenJDK Build by Oracle

These are free and unbranded versions of the OpenJDK under the GPL license with Classpath Extension (secure for business use). These builds are only available in the first six months of a release. For Java 11, the expectation is that there will be Java 11.0.0 and then two security patches, 11.0.1 and 11.0.2.

To continue using the OpenJDK build by Oracle with security patches, you would have to switch to Java 12 within a month after the launch. Note that the provision of security patches is not the same as support. Support involves paying someone to do the sorting and acting on the error reports.

3AdoptOpenJDK Build

These are free and unbranded OpenJDK builds under the GPL license with the Classpath Extension. Unlike Oracle’s OpenJDK builds, these builds will continue for a much longer period for major versions such as Java 11.

The versions of Java 11 will continue for four years, one year after the next major release. AdoptOpenJDK is a community group. They will provide builds as long as other groups create and publish security fixes to a source repository in OpenJDK. Both IBM and Red Hat have indicated that they intend to provide these security patches.

4AdoptOpenJDK OpenJ9 Build

In addition to standard OpenJDK builds, AdoptOpenJDK will also provide builds with OpenJ9 instead of HotSpot.

OpenJ9 was originally the IBM JVM, but OpenJ9 is now open source in Eclipse. This one, in fact, is something to be studied.

5Red Hat OpenJDK Build

Red Hat provides OpenJDK builds through Red Hat Enterprise Linux (RHEL), which is a commercial product with paid support. They are very good at providing security fixes back to OpenJDK.

In the past, Red Hat has run the Java 6 and 7 security update project. The Red Hat build is better integrated with the operating system, so it is not a pure OpenJDK build (no end-user JDK)

6Azul Zulu

Zulu is a branded version of OpenJDK with paid commercial support. In addition, Azul provides some Zulu constructions for free as part of the “Zulu Community;” however, there are no specific commitments regarding the availability of these free constructions.

Azul has an extensive plan to commercially support Zulu, including plans to support Java 9, 13, and 15, unlike any other vendor.

7Amazon Corretto

Among all, it is the newest option. Corretto is a no-cost build of OpenJDK with long-term support passing through the TCK. It is under the standard GPL + CE license of all versions of OpenJDK. Amazon will add its own patches and run Corretto on AWS, so it will be heavily used (it has already been placed on some products). Support for Java 8 will be at least until June 2023.

In the process of transforming OpenJDK’s source database into a building, the vendor may or may not add some branding or additional utilities as long as this does not prevent certification (TCK). For example, a provider can not add a new public method to an API or a new language resource.

Additionally, there are still other implementations of JDK, such as IBM and SAP, but by restricting their use, I ended up leaving out this short article.

Conclusion

Personally, I don’t see it as a problem to have several distributions of JDK, since each one must be passed previously in the TCK. The item to be taken care of here is precisely the adoption of a proprietary JDK (Oracle) and a free build, avoiding further headaches in the future. If you only use the default features (for example, it does not depend heavily on security updates for your business), it is good to use OpenJDK Builds by Oracle (NOT OracleJDK), as it will ensure constant updating (within six months of release) and you can use JDK in production without major problems. If your business is cloud-based (with AWS), I think it’s a good try on AWS Corretto.
