Review comment:
This change is useful to avoid clash between Apache NetBeans profiler
library and VisualVM profiler library. Both of these libraries are derived from
NetBeans 8.2 profiler library, but evolve independently. Sharing the same
directory leads to errors like:
```
java.io.IOException: Invalid HPROF version 3 loaded 2
at ...HprofHeap.<init>(HprofHeap.java)
at ...HeapFactory.loadHeap(HeapFactory.java)
at ...HeapFactory.createHeap(HeapFactory.java)
```
