Oracle strictly checks Java license, companies uninstall JDK overnight

According to reports from foreign media The Register and feedback from major companies, Oracle has recently begun to include Java in its software licensing review, with the purpose of identifying customers who are on the verge of non-compliance or have already violated regulations. Oracle’s move is In order to promote corporate payment, this is also a commonly used operation to increase payment rates.

Oracle introduced two licensing models for Java SE. In April 2019, Oracle began to charge licensing fees for the previously free Java, which required users to license commercial Java SE product paid subscription to receive patches and updates.

In September 2021, when Oracle released Java 17, they began offering a no-fee licensing model that provides free quarterly updates for three years. But this model is limited to that iteration of the version, allowing users to use it for free, even for commercial use (cannot be bundled with paid products), and does not apply to earlier versions such as Java 7, 8 and 11.

There is still a lot of confusion about Java in the market. One of the common misunderstandings is that using older versions of Java does not require a license. In fact, whether you are using a new version or an old version, as long as you download patches and updates from Oracle's website, you need a corresponding support license.

The Register stated that according to their sources, Oracle has begun auditing the Java adoption of major companies since the beginning of this year. Currently, many companies have received license management services from Oracle ( LMS) requesting information about Java usage and licensing.

Oracle will also use the authorization status of databases, middleware or applications to infer whether the Java usage reported by each enterprise is true. For example, the number of databases can reflect the number of CPUs, and one of the Java SE subscription prices is $25 per CPU per month, so it can reflect whether the number of Java SE subscriptions meets the requirements.

After learning this information, many companies have completely uninstalled overnight to avoid large bills proposed by Oracle and potential penalties for years of unpaid or underpaid fees. JDK, some of them have begun to use OpenJDK open source alternatives to deal with Oracle's audit, and some companies plan to completely replace the existing technology stack. For example, PHP, I have to say that PHP is truly open source and will never be charged!
