I am developing a set of plugins on Xtext and I package my plugins as a product with Tycho. All dependencies are resolved and there is no runtime error when I execute my plug-ins. I expect the Help system to open when I click the Help Contents menu but I get the busy circle and the parent window hangs. I have org.eclipse.help feature included in the product and all necessary plug-ins are in the product.

I see only this message in the console.
12:54:35.237 [Start Help Server] INFO org.eclipse.jetty.util.log - Logging initialized @13708ms

I can launch the Help system from my Eclipse IDE but not from the built product. Is there any indirect dependency I have to include? I am using Windows 10 with Neon 2 as my platform.

I can see the Help view with a tree of contents upon click on F1 but but clicking on a link doesn't show the details page.

I could correct the issue. The issue was not with the help system but elsewhere. We are using SLF4J and a custom appender to print log messages in a MessageConsole. We used Display.syncExec and Jetty tried to log messages and there was deadlock. Logging in the MessageConsole through Display.asyncExec fixed the issue.
