AWS server upgrade to 7.1 breaks all images

[jf]

We are currently running JasperSoft 6.4.2 hourly on AWS and when we upgrade to 7.1 we get errors after data import. 

These are the errors we experience in 7.1: 

``` 
Previously (6.4.2) we used this expression to load images: "/organizations/organization_1/Resources/Images/" + $P{REPORT_CONNECTION}.getCatalog() + "_logo.png" 

but it doesn't work any more and we get this error: 
(net.sf.jasperreports.engine.JRException: Byte data not found) 

in order to solve the issue we change the expression to "repo:" + $P{REPORT_CONNECTION}.getCatalog() + "_logo.png, uploaded the images as resource for each report and then it works. 
``` 

This is how ever not a viable solution as it is extremely time consuming. 
Any solution to this? 
Thank you
