New ImplicitObjectELResolverImpl
ImplicitObjectELResolver uses Arrays.binarySearch to check scope name.
It isn't very efficient.
It can be improved by using a map to hold the scope to scopeIndex.
Such as,
private static final Map<String, Integer> scopeMap = new HashMap<String,
Integer>();
static {
for (int i = 0; i < SCOPE_NAMES.length; i++) { scopeMap.put(SCOPE_NAMES[i],
i); }
}
More detail please check out the attachment
"ImplicitObjectELResolverImpl.java".
