Description
I noticed "nmetods" is misspelled like that in the jfr stats and also in the ./src/hotspot/share/jfr/periodic/jfrPeriodic.cpp and in ./src/hotspot/share/jfr/metadata/metadata.xml, for example  jdk.CompilerStatistics {
 startTime = 21:15:29.797
 compileCount = 3460
 bailoutCount = 5
 invalidatedCount = 0
 osrCompileCount = 50
 standardCompileCount = 3410
 osrBytesCompiled = 0 bytes
 standardBytesCompiled = 0 bytes
 nmetodsSize = 6.9 MB
 nmetodCodeSize = 4.8 MB
 peakTimeSpent = 226.000 ms
 totalTimeSpent = 8.366 s
}

Fix Request (13u): This patch is a typo fix that would mostly affect external consumers of JFR events. The patch applies cleanly. Tier1 passes. Test passes with patch and fails without

Fix Request (11u): This patch is a typo fix that would mostly affect external consumers of JFR events. The patch applies cleanly. Tier one and JFR tests passed on my machine.

This seemed to be misspelled in the original JFR integration in JDK-8199712.
