How to run Eclipse with openJDK11?

Question

How must eclipse.ini look like to make Eclipse (Photon, 2018-09 or 2018-12) run on openJDK11?

I have installed openJDK 11.0.1 and Eclipse 2018-09. I have a folder with XML jars (which seem to be required by Eclipse):

javax.xml.libs/
 javax.activation-1.2.0.jar
 jaxb-api-2.3.1.jar
 jaxb-core-2.3.0.1.jar
 jaxb-impl-2.3.1.jar

I have modified eclipse.ini to use the jdk and the libs:

-startup
plugins/org.eclipse.equinox.launcher_1.5.100.v20180827-1352.jar
--launcher.library
plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.800.v20180827-1352
-product
org.eclipse.epp.package.java.product
-showsplash
org.eclipse.epp.package.common
--launcher.defaultAction
openFile
--launcher.appendVmargs
-vm
D:/bin/jdk-11.0.1/bin
-vmargs
-cp D:/bin/javax.xml.libs/*
-Dosgi.requiredJavaVersion=1.8
[email protected]/eclipse-workspace
-XX:+UseG1GC
-XX:+UseStringDeduplication
--add-modules=ALL-DEFAULT,ALL-SYSTEM
# --add-opens=org.eclipse.mylyn.bugzilla.core
-Dosgi.dataAreaRequiresExplicitInit=true
-Xms256m
-Xmx1024m

Starting Eclipse works but leads to the following errors in workspace/.metadata/.log. Removing the comment from line 21 in eclipse.ini prevents Eclipse from starting at all. What am I doing wrong?

Answer 1

This bug is caused by the Mylyn Bugzilla connector using classes of the javax.xml.bind package that has been introduced in Java 6, but removed in Java 11 (see: JEP 320: Remove the Java EE and CORBA Modules).

In Eclipse, the Bugzilla connector is used for the following features that are broken when the mentioned error is logged each time Eclipse is started:

• Help > Report Bug or Enhancement...
• Search > Search..., tab Task Search

Unfortunately, this bug still exists in Eclipse 2018-12 in some of the IDE packages, including the Eclipse IDE for Java Developers you use (in your log as -product org.eclipse.epp.package.java.product).

Use one of the following as a workaround (tested with Eclipse 2018-12):

• Use Java 8, 9 or 10 to run Eclipse, but in Window > Preferences: Java > Installed JREs use a Java 11 JDK
• Use the Eclipse IDE for Enterprise Java Developers instead of the Eclipse IDE for Java Developers
• Copy the following JARs from Eclipse Orbit into the dropins folder of your Eclipse 2018-12 IDE:
  • javax.xml.bind 2.2.0
  • javax.activation 1.1.0
  • javax.xml 1.3

For details see my (for 2018-12 unfortunately too late) mails on the Eclipse cross-project-issues-dev mailing list here and here.
