The null null Error
By Pete Freitag
We have a global error handler setup on our site that emails us whenever an uncaught exception is thrown by ColdFusion. Ever since we upgraded to ColdFusion MX we had been randomly getting the error null null The error occurred on line 1.
thrown from our Application.cfm file. On line 1 was our cfapplication
tag. The error would be thrown from several different urls within the site, and we were never able to reproduce it - until last week.
Shortly after I started outputting cookie values in the error emails, I noticed that this error is thrown when the CFTOKEN
cookie is not defined but the CFID
cookie exists - or vise versa. You will only get this error if you have client variables turned on.
With that I was able to provide some code to reproduce the problem, and report it to Macromedia. If your having this issue you may inquire about bug 57458.
Here's the stack trace that shows up in my logs:
java.lang.NullPointerException at coldfusion.runtime.ClientScopeKey.hashCode(ClientScopeKey.java:29) at java.util.Hashtable.get(Hashtable.java:333) at coldfusion.runtime.ClientScopeServiceImpl.GetClientScope(ClientScopeServiceImpl.java:168) at coldfusion.tagext.lang.ApplicationTag.setupClientScope(ApplicationTag.java:571) at coldfusion.tagext.lang.ApplicationTag.doStartTag(ApplicationTag.java:283) at coldfusion.runtime.CfJspPage._emptyTag(CfJspPage.java:1876) at cfApplication2ecfm81526635.runPage(/web/Application.cfm:2) at coldfusion.runtime.CfJspPage.invoke(CfJspPage.java:147) at coldfusion.tagext.lang.IncludeTag.doStartTag(IncludeTag.java:357) at coldfusion.filter.CfincludeFilter.invoke(CfincludeFilter.java:62) at coldfusion.filter.CfincludeFilter.include(CfincludeFilter.java:30) at coldfusion.filter.ApplicationFilter.invoke(ApplicationFilter.java:93) at coldfusion.filter.RequestMonitorFilter.invoke(RequestMonitorFilter.java:48) at coldfusion.filter.PathFilter.invoke(PathFilter.java:80) at coldfusion.filter.ExceptionFilter.invoke(ExceptionFilter.java:47) at coldfusion.filter.ClientScopePersistenceFilter.invoke(ClientScopePersistenceFilter.java:28) at coldfusion.filter.BrowserFilter.invoke(BrowserFilter.java:35) at coldfusion.filter.GlobalsFilter.invoke(GlobalsFilter.java:43) at coldfusion.filter.DatasourceFilter.invoke(DatasourceFilter.java:22) at coldfusion.CfmServlet.service(CfmServlet.java:105) at jrun.servlet.ServletInvoker.invoke(ServletInvoker.java:91) at jrun.servlet.JRunInvokerChain.invokeNext(JRunInvokerChain.java:42) at jrun.servlet.JRunRequestDispatcher.invoke(JRunRequestDispatcher.java:249) at jrun.servlet.ServletEngineService.dispatch(ServletEngineService.java:527) at jrun.servlet.jrpp.JRunProxyService.invokeRunnable(JRunProxyService.java:192) at jrunx.scheduler.ThreadPool$DownstreamMetrics.invokeRunnable(ThreadPool.java:348) at jrunx.scheduler.ThreadPool$ThreadThrottle.invokeRunnable(ThreadPool.java:451) at jrunx.scheduler.ThreadPool$UpstreamMetrics.invokeRunnable(ThreadPool.java:294) at jrunx.scheduler.WorkerThread.run(WorkerThread.java:66)

Had MM recognized 57458 as a legit bug as of today? I could not find it on their site.
--Thanks!
We went through the per-incident tech support once before when we were having several issues (including NULL NULL) and were less than satisfied.
I changed it from using an asterisk to actually naming the columns, and the problem went away. Go figure.
Bug 57458 is a duplicate of bug 45343. This has been fixed but was not included in the CFMX 6.1 Updater -- it is included in CFMX 7.
We have a process that uses quite a few objects (components) and has some very large query data sets. Both of these stressed JRun a bit.
