[infinispan-dev] Analysis of infinispan-6.0.2 dependency on JDK-Internal APIs

Hi Galder, As part of the preparations for JDK 9, Oracle’s engineers have been analyzing open source projects like yours to understand usage. One area of concern involves identifying compatibility problems, such as reliance on JDK-internal APIs. Our engineers have already prepared guidance on migrating some of the more common usage patterns of JDK-internal APIs to supported public interfaces. The list is on the OpenJDK wiki [0], along with instructions on how to run the jdeps analysis tool yourself . As part of the ongoing development of JDK 9, I would like to encourage migration from JDK-internal APIs towards the supported Java APIs. I have prepared a report for your project rele ase infinispan-6.0.2 based on the jdeps output. The report is attached to this e-mail. For anything where your migration path is unclear, I would appreciate comments on the JDK-internal API usage patterns in the attached jdeps report - in particular comments elaborating on the rationale for them - either to me or on this mailing list. Finding suitable replacements for unsupported interfaces is not always straightforward, which is why I am reaching out to you early in the JDK 9 development cycle so you can give feedback about new APIs that may be needed to facilitate this exercise. Thank you in advance for any efforts and feedback helping us make JDK 9 better.
