Staying Oracle Java-free means more than just switching to a free distribution like Temurin, Azul, or Corretto once. It means ensuring that no Oracle Java ever makes its way onto your systems again. This must be secured technically, organizationally, and legally so that Oracle can no longer enforce its audit rights.

A migration away from Oracle Java is only audit-proof if it has been carried out completely and thoroughly: All Oracle Java installations must be identified, uninstalled, and replaced with an alternative that complies with licensing requirements. This includes not only obvious server installations but also hidden dependencies in applications, middleware components, development environments, and automated processes.
ProLicense guides you through this process—from a complete inventory of all Oracle Java installations, through a structured migration, to comprehensive documentation that serves as evidence in the event of an audit.
“Oracle has no right to conduct an audit if Oracle Java is no longer in use. But only those who can prove it are truly free.”
Markus Oberg, Java licensing expert, with ProLicense for 13 years
In addition to technical measures, organizational processes are the key factor in ensuring long-term audit compliance. Organizations without clear processes for approving and operating Java runtime environments risk Oracle Java making a comeback through the back door.
ProLicense works with you to develop a Java governance framework that ensures Oracle Java no longer has a place within your organization’s structure.
Only once you have completed your migration properly, ensured it is technically sound, and documented it thoroughly will you be in the comfortable position of being able to fend off future Oracle audits with just a single letter. Oracle no longer has the right to conduct an audit precisely when no Oracle Java is actually being used in your company.
In this situation, an audit request can be resolved with a single, legally precise letter, thereby depriving Oracle of the basis for further action. ProLicense will draft this letter for you: We know which arguments are crucial, which legal points need to be addressed, and how the letter must be worded so that Oracle has no grounds for escalation.
Many of our clients have permanently resolved Oracle audit requests in this manner without any further effort.
ProLicense guides you from the very first step (a complete inventory) all the way to lasting freedom from Oracle Java—ensuring Oracle can no longer find any leverage over you. Schedule your free initial consultation now.

1.Is uninstalling Oracle Java enough to no longer be subject to an audit?
Uninstallation is the first step, but not the last. Oracle not only checks current installations but may also inquire whether Oracle Java was used in the past. It is crucial that the transition be fully and thoroughly documented and technically secured in such a way that Oracle Java does not return via updates or dependencies. ProLicense ensures that your migration is truly audit-proof.
2.How can I find out if Oracle Java is still running on my systems?
This is often more difficult than expected. Oracle Java can be present not only in obvious server installations but also in hidden dependencies, middleware components, development environments, or as a bundled JRE in applications. ProLicense conducts a comprehensive inventory—even in areas where Oracle Java remains invisible in day-to-day operations.
3.Can Oracle automatically revert Java through updates?
Yes. In many corporate environments, Oracle Java installs itself silently in the background via automatic Java updates, bundled installations, or applications that include their own JRE. Without active technical safeguards, it is virtually impossible to keep Oracle Java from being installed permanently. ProLicense therefore recommends and assists with the implementation of appropriate monitoring and blocking measures.
4.What is a Java governance framework, and do I need one?
A Java governance framework is a set of clear processes and rules that defines which Java distributions may be used within the company, who is authorized to install JDKs, and how application vendors are evaluated for compliance with Oracle Java requirements. Experience has shown that without such processes, Oracle Java keeps reappearing through developer teams or application vendors. ProLicense develops this framework in collaboration with you.
5.Can I really resolve an Oracle audit request with just one letter?
Yes. Provided, however, that your transition is fully complete, technically secured, and thoroughly documented. In that case, Oracle simply no longer has the right to conduct an audit. A legally precise letter deprives Oracle of the basis for further action. PoLicense helps you draft this letter and knows exactly which arguments and legal points it must contain.
6.Which Java distribution does ProLicense recommend as an alternative to Oracle Java?
That depends on your specific application landscape, your support requirements, and your regulatory situation. Eclipse Temurin is free and a viable option for many companies. However, due to KRITIS guidelines, it is not suitable for every company or every industry. Azul Zulu, Amazon Corretto, Microsoft build of OpenJDK, and Red Hat OpenJDK are other alternatives, each with its own strengths. ProLicense evaluates all options for your specific context, without being tied to any particular distributor.
7.What happens if application providers require Oracle Java?
This is one of the most common entry points for Oracle Java in companies that have actually already switched. Applications that come with their own Oracle JRE or require Oracle Java as a runtime environment may trigger a licensing obligation, even if the company itself no longer has an Oracle Java contract. ProLicense analyzes your application landscape and works with you to develop processes that structurally eliminate this risk.
8.How long does a complete Oracle Java migration take?
That depends on the size and complexity of your environment. Simple environments can be migrated in a few weeks. Complex enterprise environments with many applications, dependencies, and cloud components require more time and a structured migration plan. ProLicense supports this process from the initial inventory through to the completion of the migration.
