ThreadInfoCompositeData.compositeType() broken in 11 and later

Probable fix use Runtime.version().feature() instead of 0:

public static CompositeType compositeType() {
return
ThreadInfoCompositeTypes.compositeTypes.get(Runtime.version().feature());
}

Hi,
seems with the change for
8198253: ThreadInfo.from(CompositeData) incorrectly accepts CompositeData
with missing JDK 6 attributes
ThreadInfoCompositeData.compositeType() was broken. It just returns
public static CompositeType compositeType() {
return ThreadInfoCompositeTypes.compositeTypes.get(0);
}
while ThreadInfoCompositeTypes.compositeTypes consists of
types.put(CURRENT, ctype);
types.put(5, initV5CompositeType(ctype));
types.put(6, initV6CompositeType(ctype));
so that compositeType just returns null, which further down the stack
leads to
