Jaroslav Jankovič closed JBIDE-11892.
-------------------------------------



I am not facing any JaxRSMetaModelBuilder when importing and building hibernate-search projects. Also there are not any performance issues. Verified with jbosstools-3.3_stable_branch.aggregate-Update-2012-05-27_14-14-33-H161.zip. Closing this JIRA.

> 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.

> 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.
