GlassFish server fails to launch from Eclipse, it gets stuck at 69%

I had the same problem, with the same messages.

After a long search, I gave up and I removed the server.

And I removed the Server Runtime Environment

The Glassfish files were not removed only the eclipse configurations, and then I re-created the Server Runtime and the Server using the existent glassfish server and the problem was fixed :D.

I got the same issue. I'm using Eclipse Luna.

I downgraded my GlassFish Tools to 7.2 and I got the server started back again. http://download.oracle.com/otn_software/oepe/12.1.3.1/luna/repository

I didn't see any errors in the log, just some warnings about Hibernate stuff, which shouldn't crash the launch. It could be that it is taking too long to initialize with all of the eclipse overhead, but most likely it could be a locking issue, which could cause the timeout, since eclipse would be left infinitely waiting for a resource it could never obtain. Are you sure the server is only being accessed by eclipse, and is not already running or owned by another process?
