Dan Haywood updated ISIS-1051:
------------------------------
Component/s: Core
> Only call LayoutMetadataReaderFromJson on entities
> --------------------------------------------------
>
> Key: ISIS-1051
> URL: https://issues.apache.org/jira/browse/ISIS-1051
> Project: Isis
> Issue Type: Improvement
> Components: Core
> Affects Versions: core-1.7.0
> Reporter: Dan Haywood
> Assignee: Dan Haywood
> Fix For: core-1.9.0
>
>
> Taken from a comment by Martin on ISIS-931:
> While debugging ISIS-911 I've noticed that
> org.apache.isis.core.metamodel.layoutmetadata.json.LayoutMetadataReaderFromJson#asProperties
> is expensive. It is called at start time and tries to load .layout.json file
> for every introspected method. This includes JRE classes, JDO classes, and
> many more. I think it should be called only for objects/entities. The
> expensiveness is that it tries to find a file in the classpath and if it is
> not found then it throws
> org.apache.isis.core.metamodel.layoutmetadata.LayoutMetadataReader.ReaderException.
> The stacktrace of this exception is ignored at
> org.apache.isis.core.metamodel.specloader.specimpl.FacetedMethodsBuilder#readMetadataProperties
> so
> ReaderException could override java.lang.Throwable#fillInStackTrace() to
> return null and save some time.
