It seems that bndtools is slowing down things significantly when used in a large Eclipse workspace / projects with lots of dependencies. Using the sampler VisualVM, it appears that the time is mostly spent for SHA-256 calculation.

Even when trying to shut down Eclipse, the shut down hangs because bndtools first wants to complete these SHA-256 calculations.

• It would be nice if calculations would not take so much time - maybe they can be performed lazily or maybe they can be cached?
• When Eclipse is being shut down, it would be nice if the m2e bndtools would detect this and stop their build.
