Issue Description
JDK-8345185

jpackage No Longer Includes Service Bindings by Default for Generated Run-Time Images


Starting with JDK 25, jpackage will no longer include service bindings for a run-time image that it creates. Prior to JDK 25, jpackage would include service bindings for run-time images. As a result, the generated run-time images produced by jpackage might not include the same set of modules as it did in prior versions.

The previous behavior can be achieved with the jpackage of JDK 25 by adding the --bind-services jlink option to the default jlink options jpackage uses:

` jpackage [...] --jlink-options \ "--strip-native-commands --strip-debug --no-man-pages --no-header-files --bind-services" `

Issue Description
JDK-8349637

Incorrect result of Integer.numberOfLeadingZeros


Integer.numberOfLeadingZeros may return an incorrect result on x86_64 with AVX2. The issue is caused by an incorrect JIT compiler optimization. As a workaround, the following command-line options can be used -XX:+UnlockDiagnosticVMOptions -XX:DisableIntrinsic=_numberOfLeadingZeros_i.
