Claude Brisson closed VELOCITY-812. ----------------------------------- Resolution: Invalid Assignee: Claude Brisson Fix Version/s: 2.x Since it seems to be a javacc problem, we won't fix it here: we can't do more than upgrade javacc, which has been done (we're now using javacc 5.0). > Parser.jj_scan_token very slow during debugging > ----------------------------------------------- > > Key: VELOCITY-812 > URL: https://issues.apache.org/jira/browse/VELOCITY-812 > Project: Velocity > Issue Type: Bug > Components: Engine > Affects Versions: 1.7 > Environment: linux, windows, tomcat 6 running via maven, JDK7 (but > had same issue with JDK6) > Reporter: Konstantinos Kougios > Assignee: Claude Brisson > Fix For: 2.x > > Attachments: profile.png > > > Parser.jj_scan_token runs very slowly during java debugging mode. I've > allocated more than enough memory for Java (Xmx , Xss, PermGen) and made sure > it is enough by monitoring via visualvm. > I am working on a springframework mvc project, with velocity as the template > engine. Spring has a macro file that is loaded during startup : spring.vm > (10kb). My box (6 core phenom processor) takes 10 seconds to parse that > macro. After profiling with visualvm, I found out that 9 secs are spend on > jj_scan_token method. > When running the project without debugging enabled, the parsing is very fast. > Please note that the issue occurs without any customization of velocity > properties. Typically though the properties look like this: > springMacro.resource.loader.cache=true, > resource.loader=[springMacro], > velocimacro.library=org/springframework/web/servlet/view/velocity/spring.vm, > output.encoding=UTF-8, > input.encoding=UTF-8, > springMacro.resource.loader.class=org.apache.velocity.runtime.resource.loader.ClasspathResourceLoader > Please note that I've tried removing the encoding, but still the problem > persists. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@velocity.apache.org For additional commands, e-mail: dev-h...@velocity.apache.org
