solution:
change org.apache.ibatis.type.JdbcType.codeLookup to delayed filling
private final static Map<Integer,JdbcType> codeLookup = new HashMap<>();
JdbcType(int code) {
this.TYPE_CODE = code;
}
public static JdbcType forCode(int code) {
if (codeLookup.isEmpty()) {
for (JdbcType type : JdbcType.values()) {
codeLookup.put(type.TYPE_CODE, type);
}
}
return codeLookup.get(code);
}

Mybatis provides support for different modules in both Spring Native and Quarkus, and I don't think the corresponding GraalVM json file should be added to mybatis itself.
