Issue Description
JDK-8345185

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


Starting with JDK 25, jpackage no longer includes 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 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.
