        Description

        Whe enabling -XX:+TraceGen0Time and if we get an evacuation failure, G1 gives the following error:

        # To suppress the following error report, specify this argument
        # after -XX: or in .hotspotrc: SuppressErrorAt=/numberSeq.cpp:116
        #
        # A fatal error has been detected by the Java Runtime Environment:

        # Error: guarantee(check_nums(total, n, parts),"all seq lengths should match")

        Here's a command line that can cause this (but, really, any run with evacuation failure would cause this):

        java -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -Xms32m -Xmx32m -XX:G1YoungGenSize=24m -XX:+PrintGCDetails -XX:+TraceGen0Time SpecApplication -g _213_javac
