Eclipse Build:Id: 20220609-1112
Java: 11.0.14.1
Hi all,
our RCP OSGi Application does not run anymore after upgrading to Java 11. This is because Java 11 removed javax.annotation and this leads to the following Exception while running our application:

The Eclipse Plugin for Dependency Injection "org.eclipse.e4.core.di" cannot find the javax.annotation package at runtime right after starting the application. The Application runs as mentioned in an OSGi Container. There are no unresolved requirements or something similar at Compile time, furthermore javax.annotation is present in the Build and in the target platform. See the Manifest of the org.eclipse.e4.core.di Bundle below:
Automatic-Module-Name = org.eclipse.e4.core.di
Build-Jdk-Spec = 11
Bundle-ActivationPolicy = lazy
Bundle-Localization = plugin
Bundle-ManifestVersion = 2
Bundle-Name = Eclipse Dependency Injection
Bundle-RequiredExecutionEnvironment = JavaSE-11
Bundle-SymbolicName = org.eclipse.e4.core.di
Bundle-Vendor = Eclipse.org
Bundle-Version = 1.8.200.v20220512-1957
Created-By = Maven Archiver 3.5.2
Eclipse-SourceReferences = scm:git:https://github.com/eclipse-platform/eclipse.platform.runtime.git;path="bundles/org.eclipse.e4.core.di";tag="I20220512-1800";commitId=ada015b6ae742e99f70411886c4f72f1a1fe1713
Export-Package = org.eclipse.e4.core.di;version="1.7.0",org.eclipse.e4.core.di.suppliers;version="1.7.0",org.eclipse.e4.core.internal.di;x-friends:="org.eclipse.e4.core.contexts",org.eclipse.e4.core.internal.di.osgi;x-internal:=true,org.eclipse.e4.core.internal.di.shared;x-friends:="org.eclipse.e4.core.contexts,org.eclipse.e4.core.di.extensions.supplier"
Import-Package = javax.inject;version="1.0.0",org.eclipse.osgi.framework.log;version="1.1.0",org.osgi.framework;version="1.8.0",org.osgi.util.tracker;version="1.5.1"
Manifest-Version = 1.0
Require-Bundle = org.eclipse.e4.core.di.annotations;bundle-version="[1.4.0,2.0.0)";visibility:=reexport,javax.annotation;bundle-version="[1.3.5,2.0.0)"
This Bundle requires the javax.annotation package, but does not import it.
We wonder how can we add javax.annotation to the OSGi runtime so that it is available for the dependency injection plugin? Has anybody maybe already had a similar problem?

Maybe some additional Info:
We have another Application that is built the same way and that one somehow works. We cannot really figure out why. As I understood OSGi correctly, every plugin has its own classloader and it seems like that javax.annotation is not loaded within the scope of the org.eclipse.e4.core.di plugin. Furthermore in the OSGi runtime it is visible that a javax.annotation bundle is started and active, so it should be avaiable at runtime.
