[richfaces-issues] [JBoss JIRA] Updated: (RF-4498) EndlessLoop in CssCompressor

EndlessLoop in CssCompressor ---------------------------- Key: RF-4498 URL: https://jira.jboss.org/jira/browse/RF-4498 Project: RichFaces Issue Type: Bug Affects Versions: 3.2.2 Environment: Browser independent Reporter: andreas_back Assignee: Nick Belaevski Priority: Critical Fix For: 3.3.0 When starting our application under RF 3.2.2 GA Tomcat consumes (on a Quad-Core-Processor) 25 % of the overall CPU performance, if the first page of the application is requested. After adding set CATALINA_OPTS="-Dcom.sun.management.jmxremote" to the startup.bat and starting jconsole it was found the time is consumed in line 41 of CssCompressor.java, see the code fragment. sb = new StringBuffer(srcsb.toString()); while ((startIndex = sb.indexOf("/*")) >= 0) { endIndex = sb.indexOf("*/", startIndex + 2); if (endIndex >= startIndex + 2) sb.delete(startIndex, endIndex + 2); } A simple code analysis shows that the code starts an endless loop for example for the string /*/ If the parameter org.ajax4jsf.COMPRESS_STYLE is set to false then the endless loop disappears. It could be noted that the single string in the CssCompressorTest class does not contain the comment /* or */.
