调研方向
复现 org.eclipse.core.jobs bundle 的停止和重启序列，然后从 org.eclipse.core.internal.jobs.InternalJob 和 JobManager 入手，尤其关注堆栈跟踪中显示的调度路径。检查调度新的 Job 时，重启后的 bundle 是如何表示的。完成标准是：bundle 重启后可以创建并调度 Job，并且针对所报告序列具有回归测试覆盖。

描述
Let's make sure issue is not already fixed in latest builds first.
- I verified I can reproduce this issue against latest Integration Build of Eclipse SDK
Not checked with the latest Build, but checked that the affected bundle has been unchanged compared to the version I tried with.
Steps to reproduce
- In a running application, stop the "org.eclipse.core.jobs" bundle
- restart the bundle
- create a new job
This fails with an exception
I expected: That the bundle can be stopped and restarted
But got: it becomes unusable after restarting
Looking at the failing code, it looks like the class "InternalJob" keeps a cached instance of the first ever created JobManager in a static final field and only uses that for all created instances of InternalJob instead of using the current running JobManager.

Code for reproduction
BundleContext bundleContext = FrameworkUtil.getBundle(getClass()).getBundleContext();
Bundle coreJobs = Arrays.stream( bundleContext.getBundles()).filter(x -> x.getSymbolicName().equals("org.eclipse.core.jobs")).findFirst().orElseThrow();
coreJobs.stop();
coreJobs.start();
Job job = new Job("test") {
@Override
protected IStatus run(IProgressMonitor monitor) {
return Status.OK_STATUS;
}
};
job.schedule();

- I understand reporting an issue to this OSS project does not mandate anyone to fix it. Other contributors may consider the issue, or not, at their own convenience. The most efficient way to get it fixed is that I fix it myself and contribute it back as a good quality patch to the project.
