@Internal public class JavaExceptionAnalyzer extends org.apache.lucene.analysis.Analyzer
This class wraps the given analyzer.

The Analyzer.tokenStream(String, java.io.Reader) method wraps the resulting TokenStream in the SubtokenFilter.

Note: This works on more than just Java exceptions due to the functionality implemented by SubtokenFilter (JRA-7774).

Since:
v3.12 Platform-specific class intended for the Lucene search platform only. Jira Search exposes a common API backed by multiple search engines. This class bypasses that abstraction and couples callers to Lucene internals. Using this class when the runtime search platform is not Lucene (e.g. OpenSearch) may produce incorrect results or failures. Internal use only.
