Reported problem:
1. Start a fresh Nuxeo it hangs, no error, nuxeoctl gives up (too long), server forcibily stopped
2. When restarting there is an error:
2019-07-17T17:53:25,406 ERROR [main] [org.nuxeo.runtime.model.ComponentManager] Component service:org.nuxeo.runtime.avro notification of application started failed: Invalid schema file: /var/lib/nuxeo/data/avro/BulkStatus-0x182AC639648607C7.avsc java.lang.IllegalArgumentException: Invalid schema file: /var/lib/nuxeo/data/avro/BulkStatus-0x182AC639648607C7.avsc at ... org.nuxeo.lib.stream.codec.FileAvroSchemaStore.loadSchema(FileAvroSchemaStore.java:81) ~[nuxeo-stream-10.10-HF10.jar:?] at org.nuxeo.lib.stream.codec.FileAvroSchemaStore.loadSchemas(FileAvroSchemaStore.java:67) ~[nuxeo-stream-10.10-HF10.jar:?] at org.nuxeo.lib.stream.codec.FileAvroSchemaStore.<init>(FileAvroSchemaStore.java:55) ~[nuxeo-stream-10.10-HF10.jar:?] at org.nuxeo.runtime.avro.AvroServiceImpl.<init>(AvroServiceImpl.java:73) ~[nuxeo-runtime-stream-10.10-HF08.jar:?] at
The invalid Avro schema file exists but it is empty thus invalid.
This prevents to start Nuxeo properly

Without Avro or Bulk service other NPE errors are triggered, like:
Caused by: java.lang.NullPointerExceptionCaused by: java.lang.NullPointerException at org.nuxeo.runtime.avro.AvroComponent.getAdapter(AvroComponent.java:56) ~[nuxeo-runtime-stream-10.10-HF08.jar:?]
This can be fixed by removing the empty file (/var/lib/nuxeo/data/avro/BulkStatus-0x182AC639648607C7.avsc) and restarting.
Without a thread dump, it is hard to be sure but It is possible that there is a race condition when creating the Avro Schema files, if multiple threads try to create the same schema file it could result in a deadlock with an empty file.
