humm I haven't looked at how to add that to the classpath. I will try .settings/org.eclipse.jdt.core.prefs but up to now I tried these three ways suggested in this stackoverflow post (user : Henrik Steudel post). None work.


Unfortunately the code is company code and they are pretty strict on posting code externally.

In addition to the manifest, are the .classpath and
.settings/org.eclipse.jdt.core.prefs also set to 1.8?

Do you have a minimal test case, perhaps on GitHub I can try out?
