error when using svg2png serializer

[kyle koss]

I keep getting this error from cocoon, whenever I use the svg2png serializer. I checked the archives for this, and found a few people with similar errors, but it seems none of them had a reply. The error only appears in the logs, and does not seem to cause any problems, but it is a little worrisome, as I would like it to not generate any errors at all.   Here is the error:       ERROR   (2002-09-25) 16:46.34:030   [access] (Unknown-URI) Unknown-thread/CocoonServlet: Cocoon servlet threw an Exception while trying to close stream. java.io.IOException: Cannot flush a closed output stream       at org.apache.catalina.connector.ResponseStream.flush(ResponseStream.java:241)       at org.apache.cocoon.servlet.CocoonServlet.service(CocoonServlet.java:1126)       at javax.servlet.http.HttpServlet.service(HttpServlet.java:853)       at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247)       at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:193)       at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:243)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566)       at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472)       at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943)       at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:190)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566)       at org.apache.catalina.valves.CertificatesValve.invoke(CertificatesValve.java:246)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564)       at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472)       at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943)       at org.apache.catalina.core.StandardContext.invoke(StandardContext.java:2347)       at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:180)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566)       at org.apache.catalina.valves.ErrorDispatcherValve.invoke(ErrorDispatcherValve.java:170)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564)       at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:170)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564)       at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:468)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:564)       at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472)       at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943)       at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:174)       at org.apache.catalina.core.StandardPipeline.invokeNext(StandardPipeline.java:566)       at org.apache.catalina.core.StandardPipeline.invoke(StandardPipeline.java:472)       at org.apache.catalina.core.ContainerBase.invoke(ContainerBase.java:943)       at org.apache.catalina.connector.http.HttpProcessor.process(HttpProcessor.java:1027)       at org.apache.catalina.connector.http.HttpProcessor.run(HttpProcessor.java:1125)       at java.lang.Thread.run(Thread.java:536)   My environment:             Apache Tomcat 4.0.4             Cocoon 2.0.3             Jdk1.4.0_02             Mandrake Linux 8.2   Please help, thanx, Kyle
