Bug ID: 58545

Product: Tomcat 8

Hardware: Macintosh
OS: Mac OS X 10.1
Status: NEW
Severity: trivial

Replaces inefficient use of keySet() with more efficient entrySet()
In WsHandshakeRequest...
for (String pathName : pathParams.keySet()) {
newParameters.put(pathName,
Collections.unmodifiableList(
Arrays.asList(pathParams.get(pathName))));
}
should be:
for (Entry<String,String> entry : pathParams.entrySet()) {
final String pathName = entry.getKey();
newParameters.put(pathName,
Collections.unmodifiableList(
Arrays.asList(entry.getValue())));
}
to avoid the extra lookup.
