Cfthread Error, Cannot Find File "taglib.cftId"

This bug does not seem to be fixed, but Zack1590's workaround will solve the problem. 

The issue is that getSupportedTagAttributes cannot find the correct path for /WEB-INF as getRealPath does not work inside the cfthread. Luckily the results of getSupportedTagAttributes are cached in server memory. This means that if the tags are called from outside a cfthread first they will then work fine inside the cfthread. By making sure all the custom tags are called before entering the cfthread Zack1590 is able to avoid this error.

Right before I run threads, I create the following component and run the one function on it.  It's a nice little work around.

component extends="com.adobe.coldfusion.base"

{

    public function cacheScriptObjects()

    {

        local.tags = ["CFFTP","CFHTTP","CFMAIL","CFPDF","CFQUERY","CFPOP","CFIMAP","CFFEED","CFLDAP"];

        for(local.tag in local.tags)

        {

            getSupportedTagAttributes(local.tag);

        }

    }

}

In my opinion, taglib.cftld is a sysytem file. I can imagine why ColdFusion complains. Shouldn't the path be {CF_INSTALLATION_DIR}\wwwroot\WEB-INF\cftags\META-INF\taglib.cftld instead of MYAPPDIRECTORY\WebRoot\WEB-INF\cftags\META-INF\taglib.cftld?
