NoSuchMethodException exception when using ConfigurationProperties

[chrisjs]

using GraalVM CE 19.0.2

when using ConfigurationProperties, compilation will succeed but an error is thrown at runtime. this can be reproduced by applying the below patch against the commandLinerunner sample:

diff --git a/samples/commandlinerunner/clr b/samples/commandlinerunner/clr
new file mode 100755
index 0000000..8c1b419

running the application yields the following:

We might eventually add a feature for user-provided configuration properties. Until then the workaround is easy: just add the com.example.commandlinerunner.PropTest to your META-INF/native-image/reflect-config.json.
