At some point, I had severe performance issues (all cores at 100%) while importing the projects from https://github.com/hibernate/hibernate-search.
I disabled all the JBT maven configurators to try to see if this was caused by our maven integration.
I can't tell if it's related but, during import, I saw several JAX RS Metamodel build jobs running very slowly, even though none of the hibernate search projects have the jaxrs nature or builder enabled.
jstack showed me that :

JaxrsMetamodelBuildJob doesn't seem to filter the projects elligible for JAXRS stuff.
I can't say this is the cause of the performance issues I saw (I need to do some profiling) but anyway JaxrsMetamodelBuildJob should never run for non-JAXRS enabled projects.
