I have a Fedora 29 i386 virtual machine with two versions of java installed:
java-11-openjdk.i386 (/usr/lib/jvm/java-11-openjdk-11.0.ea.28-2.fc29.i386/bin/java)
java-1.8.0-openjdk.i386 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.201.b09-6.fc29.i386/jre/bin/java)
when I run my java swing application with openjdk 8 the application works fine, while with openjdk 11 an exception is thrown:
Exception in thread "main" java.lang.UnsatisfiedLinkError: Can't load library: /usr/lib/jvm/java-11-openjdk-11.0.ea.28-2.fc29.i386/lib/libawt_xawt.so

in the new versions of java there is no backward compatibility?
