Java 13 - WARNING: An illegal reflective access operation has occurred

[plittlefield]

Just installed Java 13 using these commands in Ubuntu 16.04 LTS...

Code: Select all

sudo add-apt-repository ppa:linuxuprising/java
sudo apt-get update
sudo apt-get install oracle-java13-installer
java --version

...then using the Groovy script to process a Transmission torrent, I received this warning message...

Code: Select all

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.codehaus.groovy.vmplugin.v7.Java7$1 (file:/usr/share/filebot/jar/groovy.jar) to constructor java.lang.invoke.MethodHandles$Lookup(java.lang.Class,int)
WARNING: Please consider reporting this to the maintainers of org.codehaus.groovy.vmplugin.v7.Java7$1
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

...but it DID complete the Transmission torrent process and successfully renamed and copied the file.

Thanks.

Regards,

Paully

Well, typically, if you're on Ubuntu 16.04 then Java 8 is default, and for this case we do have the various *-jdk8 compatibility packages.


The warnings above are normal if you're running the Java 8 build with Java 13. It's a Java thing. It means nothing. If you use the Java 11+ build, then those warnings will be suppressed.

OK, thanks...

"It's a Java thing. It means nothing."

..love it.

Is there a way to suppress just the WARNING messages?

[rednoah]

Yes. If you use the latest beta then these warnings will be suppressed.

If you upgrade to the latest beta, I'd also appreciate feedback if you find issues.
