Remove org.eclipse.equinox.concurrent dependency from ECF core

[Copilot]

ECF depended on org.eclipse.equinox.concurrent for async execution primitives (IExecutor, IFuture, IProgressRunnable). This dependency is removed by implementing equivalent ECF-native interfaces in org.eclipse.ecf.core.jobs.

Changes

New Infrastructure (org.eclipse.ecf.core.jobs)

• Interfaces: IExecutor, IFuture, IProgressRunnable, ISafeProgressRunner
• Base classes: AbstractExecutor, AbstractFuture
• Implementations: JobsExecutor (Eclipse Jobs), ThreadsExecutor, ImmediateExecutor
• Support: FutureProgressMonitor, SingleOperationFuture, TimeoutException

Updated Bundles

• org.eclipse.ecf - Replaced equinox.concurrent imports
• org.eclipse.ecf.remoteservice - Updated public APIs and implementations
• org.eclipse.ecf.provider.remoteservice - Updated provider classes
• org.eclipse.ecf.discovery - Updated discovery APIs
• org.eclipse.ecf.sharedobject - Updated shared object events

MANIFEST.MF Changes

Made org.eclipse.equinox.concurrent.future imports optional (resolution:=optional) in all affected bundles.

API Impact

Public APIs now return org.eclipse.ecf.core.jobs.IFuture instead of org.eclipse.equinox.concurrent.future.IFuture:

// Before
import org.eclipse.equinox.concurrent.future.IFuture;

// After
import org.eclipse.ecf.core.jobs.IFuture;

// Usage unchanged
IFuture future = remoteService.callAsync(call);
Object result = future.get();

Method signatures remain compatible - only the package changes.

Implementation Notes

• Timeout calculations use System.nanoTime() for monotonic time handling
• AbstractFuture implements both IFuture and ISafeProgressRunner for dual-mode execution
• JobsExecutor maintains Eclipse Job scheduling semantics with progress monitoring

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• repo.eclipse.org
  • Triggering command: /usr/lib/jvm/temurin-17-jdk-amd64/bin/java /usr/lib/jvm/temurin-17-jdk-amd64/bin/java --enable-native-access=ALL-UNNAMED -classpath /usr/share/apache-maven-3.9.11/boot/plexus-classworlds-2.9.0.jar -Dclassworlds.conf=/usr/share/apache-maven-3.9.11/bin/m2.conf -Dmaven.home=/usr/share/apache-maven-3.9.11 -Dlibrary.jansi.path=/usr/share/apache-maven-3.9.11/lib/jansi-native -Dmaven.multiModuleProjectDirectory=/home/REDACTED/work/ecf/ecf org.codehaus.plexus.classworlds.launcher.Launcher clean compile -pl framework/bundles/org.eclipse.ecf -am ider.filetransfer/src/org/eclipse/ecf/provider/filetransfer/browse/URLRemoteFile.java rep ure lToFactoryMapperorigin /usr/sbin/grep grep (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

Original prompt

ECF currently has class JobsExecutor that depends on a Equinox bundle https://github.com/eclipse-equinox/equinox/tree/master/bundles/org.eclipse.equinox.concurrent and we like to get rid of that dependency.

So the task would be to factor out the dependecy, ratain as much backward compatibility as possible in the ECF codebase, possibly using modern Java 8 alternatives
