Sorry i didn't mean to give random reply. It is just today my solr configuration/schema is different now and can't get the error message.
Anyway, i rerun the test. Basically by specifying such searchcomponent and requesthandler, you won't get any error. When you query this it is fine without any debug message (of course, since no debug parameter is defined in query). http://localhost:8080/solr/titles/terms?terms=true&terms.fl=autosuggest&terms.prefix=andy&terms.mincount=1& As soon as i specify the only debug parameter i know, "debugQuery" the solr server give this error: http://localhost:8080/solr/titles/terms?terms=true&terms.fl=autosuggest&terms.prefix=andy&terms.mincount=1&debugQuery=true May 3, 2011 1:27:37 PM org.apache.solr.core.SolrCore execute INFO: [titles] webapp=/solr path=/terms params={debugQuery=true&terms.mincount=1 &terms.fl=autosuggest&terms=true&terms.prefix=andy} status=500 QTime=641 May 3, 2011 1:27:37 PM org.apache.solr.common.SolrException log SEVERE: java.lang.NullPointerException at org.apache.solr.handler.component.DebugComponent.process(DebugCompone nt.java:54) at org.apache.solr.handler.component.SearchHandler.handleRequestBody(Sea rchHandler.java:203) at org.apache.solr.handler.RequestHandlerBase.handleRequest(RequestHandl erBase.java:131) at org.apache.solr.core.SolrCore.execute(SolrCore.java:1316) at org.apache.solr.servlet.SolrDispatchFilter.execute(SolrDispatchFilter .java:338) at org.apache.solr.servlet.SolrDispatchFilter.doFilter(SolrDispatchFilte r.java:241) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(Appl icationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationF ilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperV alve.java:233) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextV alve.java:191) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.j ava:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.j ava:102) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java: 568) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineVal ve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.jav a:286) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java :845) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.proce ss(Http11Protocol.java:583) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:44 7) at java.lang.Thread.run(Thread.java:619) That is all i get.
