Opening http://www.aftonbladet.se in WebView fails almost immediately with the following error (in debug mode):

    [java] /home/tav/work/promoted/jdk8u40/jre/bin/java: symbol lookup error: /home/tav/work/jfx9-dev/artifacts/sdk/rt/lib/amd64/libjfxwebkit.so: undefined symbol: udat_open_48
    [java] Java Result: 127

There's something wrong with libicu, linked statically to the lib.

I reproduce it on Linux.
