From the Wired article: "The archive server is programmed in Java and is built using Spring Boot, an open source framework for creating Java applications. Spring Boot includes a set of features called Actuator that helps developers monitor and debug their applications. One of these features is the heap dump endpoint,"
So the heapdumps being available is a Spring Boot feature so it does not appear to be malicious.
