http://issues.apache.org/bugzilla/show_bug.cgi?id=41661 [EMAIL PROTECTED] changed: What |Removed |Added ---------------------------------------------------------------------------- Status|RESOLVED |REOPENED Resolution|INVALID | ------- Additional Comments From [EMAIL PROTECTED] 2007-02-20 16:15 ------- For each page, compilation is synchronized, but it is not synchronized between pages. This is typically not a problem because most of the state for different pages isn't shared, but the 'JspConfig' instance is via the shared 'EmbeddedServletOptions' instance. Here is the top of the stack when 'JspConfig.init()' is first called: JspConfig.init() line: 202 JspConfig.findJspProperty(String) line: 254 AntCompiler(Compiler).generateJava() line: 112 AntCompiler(Compiler).compile(boolean, boolean) line: 295 AntCompiler(Compiler).compile(boolean) line: 276 AntCompiler(Compiler).compile() line: 264 JspCompilationContext.compile() line: 563 JspServletWrapper.service(HttpServletRequest, HttpServletResponse, boolean) line: 305 JspServlet.serviceJspFile(HttpServletRequest, HttpServletResponse, String, Throwable, boolean) line: 314 JspServlet.service(HttpServletRequest, HttpServletResponse) line: 264 JspServlet(HttpServlet).service(ServletRequest, ServletResponse) line: 861 The only synchronization that occurs in that stack is in 'JspServletWrapper.service', which synchronizes on 'this'. Each page has a separate 'JspServletWrapper' instance, but all instances share a common 'EmbeddedServletOptions', which contains the 'JspConfig'. Thus, the synchronization does not protect against multiple pages being compiled simultaneously and calling 'init()' on the same 'JspConfig' instance at the same time. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
