Description Moritz Eysholdt

2011-12-02 10:23:56 EST

steps to reproduce:

1. launch a runtime workbench
2. add all example projects to the workspace in the runtime workbench
3. wailt until all projects have been built
4. delete all projects (with "delete from disk" enabled).

watch the exceptions below being thrown in the console of your host workbench.

I could not reproduce this when using just one project. Could this be a race condition between the "delete projects"-thread and a builder thread? In this context it might be worth knowing that the box I'm testing on does not have an SSD, so deleting files takes a while.
