CytoKEGG question on cytoscape-helpdesk

[AlexanderPico]

Please respond at https://groups.google.com/forum/?hl=en_US%2F#!topic/cytoscape-helpdesk/ri77keM_7Xo

I'm using the CytoKEGG app latest version in Cytoscape version 3.7.1. I have used the 'Apps -> CytoKEGG -> Search Pathways' tool. I selected a organism (human hsa) and searched for the relevant pathway (e.g. Fatty Acid Biosynthesis). Once I have chosen the pathway, I clicked open. Then I've got the following errors from the Cytoscape karaf OSGi command line environment (see below), and no KEGG network was being downloaded. Please note that doing the same with an older version of Cytoscape v3.6.1, the app still works properly without problems. I'm currently using Java(TM) SE Runtime Environment (build 1.8.0_201-b09). Would you please let me know if it is an error that I could fix on my end (other than using the older versin of Cytoscape or rather it requires an update to fixt this?

This is a known issue for all applications accessing external DTD from an XML file. It can be fixed by setting Java system prop to allow this access.
