Alignment bug with OpenJDK 25 on 32 bit ARM

[hendrikdonner]

Describe the bug
OpenJDK 25 on 32 bit ARM compiled with JIT support crashes due to wrong alignment, see logs below.

To Reproduce
Running the sqlite-jdbc test suite with mvn test on OpenJDK 25 with JIT support on 32 bit ARM.

Expected behavior
No JVM crash.

Logs

jvm_crash.log

Environment (please complete the following information):

• OS: Linux
• CPU architecture: 32 bit Arm
• sqlite-jdbc version: 3.51.1.0

Additional context
Initially reported to OpenJDK, they told me to report to sqlite-jdbc. Does not occur with OpenJDK 17 nor 21, haven't tested other versions yet.

So far we can't reproduce this. CI runs some containers on armv7, but so far I haven't managed to update this job to use JDK25 because of some TLS1.3 issues that make Maven fail to retrieve artifacts from Central.

[hendrikdonner]

The original report was on OpenJDK 25.0.1, still see this on 25.0.2.

Somehow upgrading to JDK 25 for our armv7 build on CI makes the tests much longer to run. This is a test run and it took 1h to run the tests: https://github.com/xerial/sqlite-jdbc/actions/runs/22612946394/job/65519049039

however, all tests are green.

I see the CI is on Ubuntu, does Ubuntu enable the JIT on armhf? To my knowledge they do not although it's been around since OpenJDK 11.

Debian does not build with JIT support on armhf: https://salsa.debian.org/openjdk-team/openjdk/-/blob/openjdk-25/debian/rules#L63

Without an easy way to reproduce it will be very hard to troubleshoot.
