RFR: 8360143: ProblemList runtime/NMT/VirtualAllocTestType.java

[Daniel D. Daugherty]

A trivial fix to ProblemList runtime/NMT/VirtualAllocTestType.java on all platforms.

Yes, there is a fix for [JDK-8359959](https://bugs.openjdk.org/browse/JDK-8359959) out for review, but that fix won't likely
integrate until next week and I want to reduce the noise for the weekend.
