WIP: Lucene Upgrade

[fabriziofortino]

Updates Log

• 4.7.2
  • No significant changes
• 4.8.0
  • Various minimal API changes (eg: package location)
  • IndexWriter.addDocument will now throw an IllegalArgumentException if a Term to be indexed exceeds IndexWriter.MAX_TERM_LENGTH. This requires truncating index types string properties.
  • OAKIndexOutput has to implement the getChecksum() method that needs to return the CRC32 checksum of the written bytes.
• 4.8.1
  • No significant changes
• 4.9.0
  • [BREAKING] The OakCodec is not compatible with this version. This custom codec was introduced with https://issues.apache.org/jira/browse/OAK-2853 to improve performance. Over the years Lucene has drastically improved the way files are read/written. Having a custom codec and making it configurable in the index definition makes it difficult to upgrade to newer versions. Commit 762b23f removes the OakCodec and the logic to customize it.
• 4.9.1 / 4.10.0 / 4.10.1 / 4.10.2 / 4.10.3 / 4.10.4
  • No significant changes

Since the update to version 4.8.0, the baseline check fails.
