[native-image] Error with Micronaut Data and SQL Server

[ilopmar]

I've tried to build a Micronaut Data native-image application with SQL Server support but it fails during the native image creation unless I add the flag --report-unsupported-elements-at-runtime (which is discouraged).

Then, it fails during execution.

Steps to reproduce the issue:

• git clone https://github.com/micronaut-graal-tests/micronaut-data-jdbc-graal
• cd micronaut-data-jdbc-graal
• git checkout sqlserver
• Use GraalVM from master branch for JDK8
• ./build-native-image.sh

The error is:

To diagnose the issue, you can add the option --report-unsupported-elements-at-runtime. The unsupported element is then reported at run time when it is accessed the first time.

Error: Use -H:+ReportExceptionStackTraces to print stacktrace of underlying exception
Error: Image build request failed with exit status 1

I've tried initializing a few classes at run-time/build-time but it's not working. I'm not really sure if this is a bug on GraalVM side or something with the SQL Server JDBC driver.

As mentioned before if I add --report-unsupported-elements-at-runtime I can build the native-image.
For everything to work you need to start SQL Server with:

docker run -it --rm -e 'ACCEPT_EULA=Y' -e 'SA_PASSWORD=My!Secret123' -e 'MSSQL_PID=Express' -p 1433:1433 mcr.microsoft.com/mssql/server:2017-latest-ubuntu

And then:

One final thing I've tried is using the native-image Java Agent to generate all the config files but the result is the same in both cases: unable to build the native-image without --report-unsupported-elements-at-runtime and same error at runtime with it.

[ilopmar]

The last error can be fixed adding -H:+AddAllCharsets. Then the application starts and works (and least for my simple tests), but the --report-unsupported-elements-at-runtime is still neccesary.

If you want to reproduce the issue, please use the branch master_sqlserver, then edit the native-image.properties and remove the --report-unsupported-elements-at-runtime flag.
When building the native image with lastest GraalVM build from master branch (ebcf391), the error is:

I get the exact same error as above.

Using:
Micronaut 3.1.0
'com.microsoft.sqlserver:mssql-jdbc:9.4.0.jre11'
'org.jetbrains.exposed:exposed-core:0.35.1'
'org.jetbrains.exposed:exposed-jdbc:0.35.1'
'org.jetbrains.exposed:exposed-java-time:0.35.1'
'org.jetbrains.exposed:exposed-dao:0.35.1'

Adding '-H:AddAllCharsets' unfortunately does not seem to work.

Only adding '--report-unsupported-elements-at-runtime', ' --allow-incomplete-classpath' as arguments work for me which I'd like to avoid if possible

[ilopmar]

@peterscardera You don't need to add --allow-incomplete-classpath yourself, Micronaut already does that and it's mandatory for Micronaut to work with GraalVM. This is because we have @Requires(...) all over the place in Micronaut and those requirement can be on a class that may not be present on the classpath.

Regarding --report-unsupported-elements-at-runtime, I'm afraid it's still necessary (I've just tried), and that's why I opened this issue in the first place.

[fniephaus]

I have addressed this in #6089 and --report-unsupported-elements-at-runtime should no longer be needed. Please feel free to verify that this is the case using a dev build in a couple of hours.
