Scalability Issues (Che-in-Che)

[tsmaeder]

There are a couple of issues related to che-in-che(6) that cannot be solved simple on the Che side. Currently, the approach in VSCode-Java is to assume that the projects in the "workspace" are static, in particular, no new projects are detected if they are added to an open folder in the workspace (see also #144).
In Che6, importing new projects into "the workspace" is a common occurrence. The test case in question is importing the source code from https://github.com/eclipse/che into a workspace. This takes a long time and the workspace does not provide Java related functionality until the initialization phase is over. There are a couple of things we could do to improve things, in particular:

• Initialization and Workspace Update should not lock Workspace Initialization and Workspace Update should not lock Workspace #860
• Performance issues when adding lots of files Performance issues when adding lots of files #824
