LUCENE-5388 AbstractMethodError

Hi,

We have a developement environment running trunk but have custom analyzers and token filters built on 4.6.1. Now the constructors have changes somewhat and stuff breaks. Here's a consumer trying to get a TokenStream from an Analyzer object doing TokenStream stream = analyzer.tokenStream(null, new StringReader(input)); throwing:

Caused by: java.lang.AbstractMethodError
	at org.apache.lucene.analysis.Analyzer.tokenStream(Analyzer.java:140)

Changing the constructors won't work either because on 4.x we must override that specific method: analyzer is not abstract and does not override abstract method createComponents(String,Reader) in Analyzer :)

So, any hints on how to deal with this thing? Wait for 4.x backport of 5388, so something clever like <...> fill in the blanks.

Many thanks,
Markus
