We have an embedded modeshape instance (Modeshape ver.4.5  with Infinispan cache and binary file system store) , running as a microservice. When i restarted the service recently i am getting the following exception:

Caused by: javax.jcr.RepositoryException: org.modeshape.jcr.cache.DocumentAlreadyExistsException: b54f2d5b765f1a0/jcr:system/jcrNodeTypes/nt:base.

After this, it does not start and shuts down the engine. This has been working for past few months and suddenly this happened in our "user testing" environment. Any idea on how to overcome this issue or how to recover the documents already stored in this repository. Appreciate if anyone can help. Thanks.
