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
