For Removal

Element	Description
org.apache.lucene.analysis.StopwordAnalyzerBase.loadStopwordSet(boolean, Class<? extends Analyzer>, String, String)	Class.getResourceAsStream(String) is caller sensitive and cannot load resources across Java Modules. Please call the getResourceAsStream() and WordlistLoader.getWordSet(Reader, String, CharArraySet) or other methods directly.
org.apache.lucene.store.MMapDirectory.setUseUnmap(boolean)	Please use new system property MMapDirectory.ENABLE_UNMAP_HACK_SYSPROP instead
org.apache.lucene.util.IOUtils.getDecodingReader(Class<?>, String, Charset)	Class.getResourceAsStream(String) is caller sensitive and cannot load resources across Java Modules. Please call the getResourceAsStream() directly and use IOUtils.requireResourceNonNull(Object,String) to signal missing resources null
org.apache.lucene.util.IOUtils.IOConsumer	was replaced by IOConsumer.
org.apache.lucene.util.IOUtils.IOFunction	was replaced by IOFunction.

Methods

Method	Description
org.apache.lucene.analysis.StopwordAnalyzerBase.loadStopwordSet(boolean, Class<? extends Analyzer>, String, String)	Class.getResourceAsStream(String) is caller sensitive and cannot load resources across Java Modules.

org.apache.lucene.index.CodecReader.document(int, StoredFieldVisitor)
org.apache.lucene.index.CodecReader.getTermVectors(int)
org.apache.lucene.index.FilterCodecReader.document(int, StoredFieldVisitor)
org.apache.lucene.index.FilterCodecReader.getTermVectors(int)
org.apache.lucene.index.IndexReader.document(int, StoredFieldVisitor)	use IndexReader.storedFields() to retrieve one or more documents
org.apache.lucene.index.IndexReader.getTermVector(int, String)	use IndexReader.termVectors() to retrieve one or more documents
org.apache.lucene.index.IndexReader.getTermVectors(int)	use IndexReader.termVectors() to retrieve one or more documents

org.apache.lucene.search.IndexSearcher.doc(int)	Use IndexSearcher.storedFields() to access fields for one or more documents
org.apache.lucene.search.MultiTermQuery.setRewriteMethod(MultiTermQuery.RewriteMethod)	set this using a constructor instead
org.apache.lucene.search.SortField.getOptimizeSortWithIndexedData()
org.apache.lucene.search.SortField.getOptimizeSortWithPoints()	This is a duplicate method for SortField#getOptimizeSortWithIndexedData.
org.apache.lucene.search.SortField.setOptimizeSortWithIndexedData(boolean)	should only be used for compatibility with 8.x indices that got created with inconsistent data across fields, or the wrong sort configuration in the index sort
org.apache.lucene.search.SortField.setOptimizeSortWithPoints(boolean)	should only be used for compatibility with 8.x indices that got created with inconsistent data across fields, or the wrong sort configuration in the index sort. This is a duplicate method for SortField#setOptimizeSortWithIndexedData.
org.apache.lucene.search.TermInSetQuery.getTermData()	the encoded terms will no longer be exposed in a future major version; this is an implementation detail that could change at some point and shouldn't be relied on directly
org.apache.lucene.store.MMapDirectory.getPreload()	This information is no longer reliable now that preloading is more granularly configured via a predicate.
org.apache.lucene.store.MMapDirectory.getUseUnmap()	use MMapDirectory.UNMAP_SUPPORTED
org.apache.lucene.store.MMapDirectory.setPreload(boolean)	Use MMapDirectory.setPreload(BiPredicate) instead which provides more granular control.
