How to handle OpenJDK patches 

As WebSphere Liberty is supported by IBM it supports afaik only IBM JDK and Semery runtime. The following link https://www.ibm.com/support/pages/ibm-java-sdks-websphere-liberty seems to support that. If you'd like to use OpenJDK you'd need to use Open Liberty and see how to get support there. The information at https://www.ibm.com/products/support-for-runtimes   and https://openliberty.io/support/ might be helful here.

WebSphere Liberty 23.0.0.6 supports all Java versions that support the SE 8.0, SE 11 or SE 17 specification, see tab Supported Software at https://www.ibm.com/software/reports/compatibility/clarity-reports/report/html/softwareReqsForProduct?deliverableId=D65B8195F0EB42239AA7B5858DD3E9A8&osPlatforms=AIX|IBM%20i|Linux|Mac%20OS|Windows|z/OS&duComponentIds=S003|S005|S002|S006|S001|S004|C007|C008&mandatoryCapIds=13&optionalCapIds=341|9|39|8|132|20|223|26|40

The entitlement for WebSphere Liberty includes as supporting program IBM Runtimes for Business, see
https://www.ibm.com/support/customer/csol/terms/?id=L-SDZR-AQ2Q2S&lc=en#detail-document

IBM Runtimes for Business supports OpenJDK 8, OpenJDK 11 and OpenJDK 17 binaries distributed by the AdoptOpenJDK community (AdoptOpenJDK), Eclipse Adoptium (Temurin) and IBM (Semeru Runtimes).
For details, see https://www.ibm.com/products/support-for-runtimes

So basically it depends on the OpenJDK version and distribution that you use if support for the JDK is part of the WebSphere entitlement or not.

Hope that helps.
