Why is java using 1000% of my CPU when running a single-threaded tool in gatk-protected.jar?

I am running a tool that definitely only uses one core. However, when I look at top I see that I am using a large portion of the available cores on the machine.

    You may need to limit the maximum number of garbage collection threads being used by Java.

    For example:
    java -XX:ConcGCThreads=1 -jar gatk-protected.jar .......
