Description
The SPECjvm2008-Serial benchmark is showing a performance regression on Solaris-SPARCv9 in the Aurora-Performance system. When run with the default parallel garbage collector, it's showing a -1.6% statistically significant regression, and a -1.5% statistically significant regression when running with the G1 garbage collector.
Comments
Caused by JDK-8060252.

Confirmed a -1.7% regression on specjvm2008:serial on SPARC T4, running without G1 GC. It might be similar to JDK-8058353, checking that one first.
