> 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: Mikhail Vitenkov
> 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 */.
