    A FR test crawl got a flurry (4) of these at the beginning: Title: Problem occured processing '' Time: Dec. 21, 2004 02:13:14 GMT Level: SEVERE Message: Problem java.lang.NullPointerException occured when trying to process '' at step ABOUT_TO_BEGIN_PROCESSOR Associated Throwable: java.lang.NullPointerException Stacktrace: java.lang.NullPointerException at org.archive.util.TextUtils.freeMatcher( at org.archive.util.TextUtils.matches( at org.archive.crawler.filter.URIRegExpFilter.innerAccepts(URIRegExpFilter.jav a:73) at org.archive.crawler.framework.Filter.accepts( at org.archive.crawler.filter.OrFilter.innerAccepts( at org.archive.crawler.framework.Filter.accepts( at org.archive.crawler.framework.CrawlScope.excludeAccepts( ) at org.archive.crawler.framework.CrawlScope.innerAccepts( at org.archive.crawler.framework.Filter.accepts( at org.archive.crawler.prefetch.Preselector.innerProcess( at org.archive.crawler.framework.Processor.process( at org.archive.crawler.framework.ToeThread.processCrawlUri( at Looks like another variant of [ 1002760 ] NPE in TextUtils.getMatcher -- 3833&atid=539099 I think Stack's comment of 2004-11-12 12:09, that the put to both the patterns and the patternMatchers maps needs to be atomic, is the root of the problem, and the eventual null-check fix for 1002760 only works-around the problem.
