reta opened a new issue, #11788: URL: https://github.com/apache/lucene/issues/11788
### Description The Apache Lucene is using quite old version of ANTLR 4.5.1-1. By itseld, it is not a showstopper, but more profound issue is that some ANTLR 3.x bits are used [1]. Since ANTLR 4.10.x (or even earlier), the compatibility layer with `3.x` release line has been dropped in `4.x` (see please [2]), which makes Apache Lucene impossile to use with recent ANTLR 4.10.x+ releases [3]. The sample exception is below. ``` > java.lang.UnsupportedOperationException: java.io.InvalidClassException: org.antlr.v4.runtime.atn.ATN; Could not deserialize ATN with version 3 (expected 4). > at org.antlr.antlr4.runtime@4.11.1/org.antlr.v4.runtime.atn.ATNDeserializer.deserialize(ATNDeserializer.java:56) > at org.antlr.antlr4.runtime@4.11.1/org.antlr.v4.runtime.atn.ATNDeserializer.deserialize(ATNDeserializer.java:48) > at org.apache.lucene.expressions@10.0.0-SNAPSHOT/org.apache.lucene.expressions.js.JavascriptLexer.<clinit>(JavascriptLexer.java:279) ``` [1] https://github.com/apache/lucene/blob/main/lucene/expressions/src/java/org/apache/lucene/expressions/js/JavascriptLexer.java#L189 [2] https://github.com/antlr/antlr4/commit/c68e127a7cf14470565d6e6ae1eff06db3e56ea7 [3] https://github.com/opensearch-project/OpenSearch/pull/4546 @uschindler @jpountz any objections in migrating to ANTLR `4.11.1`? I would be happy to offer my help here, thank you. -- This is an automated message from the Apache Git Service.
