question: protected IntList addMetadata ( ArrayList < MetaData > metadata ) { if ( keepEmbed ) return super . addMetadata ( metadata ) ; IntList metaDataIndices = null ; if ( ( metadata != null ) && ( metadata . size ( ) > 0 ) ) { metaDataIndices = new IntList ( metadata . size ( ) ) ; for ( MetaData metaData : metadata ) { String id = metaData . id ; if ( ! id . equals ( StandardDefs .

target:  Overrides ActionBlockEmitter's addMetadata() to add support for filtering out Embed metadata, because it can contain system paths.  See SDK-25385.  In the future, we might want to go further to filter out all metadata that is only necessary at compile time for libraries or at runtime for Applications.  We already handle non-debug applications in PostLink.
