In the current stable release 4.5.4.017, when an exception is thrown the template file paths shown for each item in the TagContext array have changed from absolute to relative.
Expected value for exception.TagContext[ 1 ].template : C:\context\path\thisfile.cfm
Actual value: /path/thisfile.cfm
This breaks TestBox which expects an absolute template path when reporting failed tests.
I expect this is related to https://luceeserver.atlassian.net/browse/LDEV-1036
Rolling back to 4.5.3.020 fixes the issue.
