stackoverflowerror for json file

Question

Hello,

I downloaded the json file from here: https://www.catnmsplan.com/sites/default/files/2021-09/9.7.21-IM-4.0.0.json

I added the beginning and end markers for @startjson and @endjson.

Then I run the command line java -jar plantuml.jar CAT.json

and it processes for a few minutes and then gives me the following:

Exception in thread "main" java.lang.StackOverflowError

    at gen.lib.common.ns__c.dfs_enter_inedge(ns__c.java:370)

    at gen.lib.common.ns__c.dfs_enter_inedge(ns__c.java:384)
    at gen.lib.common.ns__c.dfs_enter_inedge(ns__c.java:384)

Are there any workarounds on this?

That's 20,000 lines of json.... what sort of meaning are you trying to extract?

For example, here is a subset of your file, just 700 lines and already unreadable:

Current limit is 9999:
