The Liberty-for-Java buildpack v3.32 now includes Liberty runtime 19.0.0.5, IBM Small Footprint JRE 8.0.5.35 and AdoptOpenJDK 11 OpenJ9 JRE 11.03.
The buildpack contains two production versions of Liberty. It provides the latest release (19.0.0.5), as well as a constant default version (19.0.0.3) for approximately three months.
To use the v19.0.0.5 Liberty release, follow these instructions.
To use the OpenJ9 JRE, set the JBP_CONFIG_IBMJDK environment variable to “version: 11.+”.
An existing application will not be affected by the new buildpack until you redeploy it. After your redeployment, existing applications should continue to run “as is” without any additional changes. New applications will automatically use the new buildpack.
