Description

Recent builds of GraalVM for JDK 25 fail with the following error:

This is using JDK 25+18 and Graal master at revision 6da4e92

Upstream GraalVM uses JDK 25+17 still it seems. The fix might be to remove the dependency or do a similar fix to #834

[jerboaa]

Looks like oracle#11020 added the dependency.

[jerboaa]

The jar providing that module is svm-capnproto-runtime.jar

[jerboaa]

The fix should be to add the new dep into the lib/svm/builder directory so that it'll get picked up by the native-image driver.
