Project to test if carmine can be used in a native binary image with GraalVM.

openjdk version "11.0.10" 2021-01-19
OpenJDK Runtime Environment GraalVM CE 21.0.0.2 (build 11.0.10+8-jvmci-21.0-b06)
OpenJDK 64-Bit Server VM GraalVM CE 21.0.0.2 (build 11.0.10+8-jvmci-21.0-b06, mixed mode, sharing)

Currently testing:

[com.taoensso/carmine "3.1.0"]

Test with:

lein do clean, uberjar, native, run-native

Building a native image that contains carmine in it requires some extra work. Since carmine uses dynamic class loading to load org.apache.commons.pool2.impl.EvictionPolicy, so we'll need to supply a reflection configuration file to GraalVM in order for it to load the class at runtime.

Add this to a file named reflect-config.json and add it to your GraalVM configuration directory:

[
  {
    "name":"org.apache.commons.pool2.impl.DefaultEvictionPolicy",
    "allPublicConstructors" : true
  }
]

and when building the native image use:

native-image -H:ConfigurationFileDirectories=./path/to/config/dir
