Java 9: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector
With Java 9 or 10, using
<dependency>
<groupId>org.glassfish.jaxb</groupId>
<artifactId>jaxb-runtime</artifactId>
<version>2.3.0</version>
</dependency>
results in:
WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector
(file: repository/org/glassfish/jaxb/jaxb-runtime/2.3.0/jaxb-runtime-2.3.0.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int)
WARNING: Please consider reporting this to the maintainers of com.sun.xml.bind.v2.runtime.reflect.opt.Injector
WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release
jaxb-ri runtime uses ClassLoader#defineClass / Unsafe#defineClass to do
some bytecode modification in runtime to optimize performance.
ClassLoader#defineClass is tried first which causes the warning.
This legacy optimization is removed completely in jaxb-ri master (after 2.3.0, not released yet).
To disable this optimization for 2.3.0, set system property
com.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize.

Hi Roman,
When I try to run with Java 9 I have the following behavior:
java -XX:+IgnoreUnrecognizedVMOptions --add-modules java.activation -cp ":./otherJars/" com.package.Main "$@"
WARNING: An illegal reflective access operation has occurred WARNING: Illegal reflective access by com.sun.xml.bind.v2.runtime.reflect.opt.Injector (file:/.../jaxb-impl.jar) to method java.lang.ClassLoader.defineClass(java.lang.String,byte[],int,int) WARNING: Please consider reporting this to the maintainers of com.sun.xml.bind.v2.runtime.reflect.opt.Injector WARNING: Use --illegal-access=warn to enable warnings of further illegal reflective access operations WARNING: All illegal access operations will be denied in a future release
And when I used noOptimize I still have some messages:
java -XX:+IgnoreUnrecognizedVMOptions -Dcom.sun.xml.bind.v2.bytecode.ClassTailor.noOptimize=true --add-modules java.activation -cp ":./otherJars/" com.package.Main "$@"

Do you know how to escape these messages?
The current intent for Oracle is to remove the java.se.ee modules starting with a future release which apparently is Java 11, this means we will not be able to use anymore JAXB(javax.xml.bind module).
How I can be procced further I need to change the library completely already now(find a replacement for JAXB) in order to be compatible with Java 11+ or use JAXB for Java 9 and 10 and look in the future for Java 11 solution, keep in mind java 11 will be released soon(around the end of this year). https://jaxenter.com/jdk-11-java-ee-modules-140674.html

Hi Corneliu,
as I posted here: https://stackoverflow.com/questions/50237516/proper-fix-for-java-10-complaining-about-illegal-reflection-access-by-jaxb-impl Runtime code optimizaton is removed in master branch and will ship with next release. Updating to new version will remove both messages. and .noOptimize flag. Next version will be usable with Java 11, which has excluded java.xml.bind and java.xml.ws modules.
