Bug ID: 1677713
           Summary: Eclipse is not compatible with jdk11
           Product: Fedora
           Version: 28

Now eclipse-platform has a dependency on java-headless, which is not
provided by java-openjdk-headless-11 but is provided by
java-1.8.0-openjdk-headless.  So the correct Java is there if 
Eclipse will use it.  It seems to me that if Eclipse is going
to be picky about the Java version then it should be a bit
more selective and not just choose the first one on my PATH.

java-openjdk-headless-12.0.0.33-1.ea.1.rolling.fc29.x86_64
java-11-openjdk-headless-11.0.2.7-0.fc29.x86_64

$ rpm -q eclipse-platform
eclipse-platform-4.10.0-2.fc29.x86_64

Eclipse reports that it has been started with Java 11.

Nevertheless, it is not (yet?) possible to uninstall java-1.8.0-openjdk. Do you
know why?

Unfortunately I plan no further Eclipse updates to F28.

F28 will be EOL soon after F30 is released so I would advise you to update to
F29 at this time.

Java 11 had a major change (removal of Enterprise Edition APIs) and not all
upstream projects have adapted yet to this. Many many projects and libraries
still need to be patched to accomodate for this.

OpenJDK 8 is still default JDK in all supported Fedora versions. Many core
applications require it. These application were not tested with JDK 11.

As Java 11 is the next LTS version, wouldn't it make sense to have a plan to
move to Java 11?

Maybe. But this bug is not the right place do discuss such plans. That's up to
maintainers of OpenJDK and Javapackages.
