Eclipse application won't run with OpenJDK 11 [message #1805247]

Hi together,
I am stuck with this issue for days now, maybe someone can help me here...
I have an application that I am able to run with Oracle Java 8 jre. Now we got the information, that due to the changes in licensing, we should migrate to OpenJDK and that these two JREs should be interchangeable. I now added the OpenJRE to the installed JREs and in the run configurations selected it as my runtime JRE. When I now run this application I get the error message which can be found in the attached log.. I used to develop in Eclipse 4.9 but also tested it with Eclipse 4.11.0 which results in the same error...
What do I have to change in my configuration, to be able to run the same application with OpenJRE? I don't really know hot to deal with the errors in the log.
Any help would be appreciated...

Best regards

Your target platform seems to be Indigo, which predates even Java 7. Perhaps it's time to update it. Alternately, are you passing it the options that Java 9 and newer need? https://wiki.eclipse.org/Configure_Eclipse_for_Java_9

Thank you for the quick reply!
We tried to avoid upgrading our eclipse because we are very short on time and hoped we could get it to run this way...
Do you think it could be a problem that we're using a 64 bit OpenJRE?
Attached you find the eclipse.ini.

I doubt it. Supplying the newer --add-modules=ALL-SYSTEM argument while still having the eclipse.ini point to jdk1.6.0_31 might cause issues of its own.

In the meantime I changed this to the openjdk installation directory... But it results in the same error...

You're using really very old stuff. It's 8 years old. An 8 year old version of Eclipse will definitely not run on Java 11. In fact Java 11 removed a bunch of things, or made them hard to use/find, e.g., any dependencies on javax.* things is problematic now. Why do you want to use a brand new JDK and an 8 year old version of Eclipse?

The problem for us is that we don't really have the time/budget to do an eclipse upgrade and the customers requirements force us to switch to OpenJDK now. We hoped we could somehow re-use our existing version and deal with this update later.

Is the log output identical to what's posted above? And just what do you mean by "changed this to the openjdk installation directory"?

I think the error is the same, see attached log file and current eclipse.ini.

I really think you are on a dead end path. I don't think such an old version of Equinox can deal with how to read the information from a Java 11 JDK/JRE. Just look at all these bugs related to equinox not working with Java 9 (i.e., when Java was first modularized):

https://bugs.eclipse.org/bugs/buglist.cgi?classification=Eclipse&list_id=18628183&product=Equinox&query_format=advanced&short_desc=java%209&short_desc_type=allwordssubstr

So I think you have two options. Update your application to the latest target platform or use an older version of Java to run your out-dated application.

I'm starting to come to same conclusion as Ed, but would be remiss to not point out that https://adoptopenjdk.net/ and others are making--and will be maintaining--OpenJDK 8 builds for some time.

Thank you for your answers!
We need to use the new OpenJDK 11 due to customers requirements...So I guess our only option is to upgrade our eclipse.
We will have to check how to do this.
