# [DRILL-8446](https://issues.apache.org/jira/browse/DRILL-8446): Incorrect
use of OperatingSystemMXBean
## Description
Simplify CpuGaugeSet fixing the non-Sun/Oracle code path in the process.
Even though code to handle non-Sun/Oracle runtimes for the
OperatingSystemMXBean was present, it would still cause them to attempt to load
a class from com.sun.management causing a NoClassDefFoundError.
## Documentation
N/A
## Testing
Launch Drill and check the affected gauges in
- OpenJDK 64-Bit Server VM (build 17.0.9+9-Debian-1, mixed mode, sharing)
- IBM J9 VM (build 2.9, JRE 1.8.0 Linux amd64-64-Bit Compressed References
