A few weeks ago I reported about my experiences with JDeveloper 11g PS6 in Malta. I had to borrow a laptop to do the Adaptive Case Management workshop. It was a HP laptop with Ubuntu 12. Somehow this combination with VirtualBox 4.3.6 lead into a bug in JDeveloper. Creating a new project would introduce a dash ('-') in the ID of each created activity.
In the mean time I have a new laptop, a very nice Asus N56. This morning I was in the opportunity to startup the VM that I exported and backed up from the borrowed laptop. And what a surprise: creating a new project just works! No naming conflicts. Also, of course, creating a new activity is ok.
A strange case indeed.
