Add error handler for NoClassDefFoundError (see luontola#1) and argument to add custom packages to ignore with ignore-file.
So for example if you have a file called agent-ignore.txt with contents:
io.netty
And you add to your normal invocation:
$GRAALVM_HOME/bin/java -javaagent:clojure-native-image-agent.jar=...,ignore-file=agent-ignore.txt ...
You will see this in your output:
clojure-native-image-agent: Loading custom ignore packages from agent-ignore.txt
clojure-native-image-agent: Loaded 1 custom ignore packages from agent-ignore.txt
clojure-native-image-agent: Custom ignore io.netty
and the packages will be excluded from your config.
