Illegal reflective access in geotools

[naoliv]

I was testing a preset only when I saw this in the console:

2017-10-05 23:55:57.660 INFO: Disposing class org.geotools.referencing.factory.epsg.ThreadedHsqlEpsgFactory backing store

[Don-vip]

what where you doing? Opening a shapefile?

[Don-vip]

Could you please run JOSM with --illegal-access=deny option? You should get a crash/bug report.

In 12932/josm:

fix #15406 - add more java9 options for geotools plugin

[naoliv]

Sorry for the delayed answer.
I am seeing a new message:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.geotools.resources.NIOUtilities (file:/home/naoliv/.josm/plugins/geotools.jar) to method java.nio.DirectByteBuffer.cleaner()
WARNING: Please consider reporting this to the maintainers of org.geotools.resources.NIOUtilities
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's strange that I can't see anything when using --illegal-access=deny
With --illegal-access=warn I see:

WARNING: Illegal reflective access by org.geotools.resources.NIOUtilities (file:/home/naoliv/.josm/plugins/geotools.jar) to method java.nio.DirectByteBuffer.cleaner()
WARNING: Illegal reflective access by org.geotools.resources.NIOUtilities (file:/home/naoliv/.josm/plugins/geotools.jar) to method java.nio.DirectByteBuffer.cleaner()

This time I am opening 2 shapefiles.

[Don-vip]

How do you run JOSM? You shouldn't see this warning.

[naoliv]

Running it with:

export _JAVA_OPTIONS="-Dawt.useSystemAAFontSettings=on -Xms256M -Xmx3g"
java --illegal-access=warn --add-modules java.se.ee -jar /home/naoliv/josm-jar/josm-latest.jar "$@"

[Don-vip]

OK I forgot something on server, this should be fixed in next latest.
