A DESCRIPTION OF THE PROBLEM :
In recent snapshot of OpenJDK 9, there is an potential buggy code in dev/jaxp/src/java.xml/share/classes/com/sun/org/apache/xalan/internal/xsltc/compiler/util/MethodGenerator.java

Code:
====
501 for (int i = 0; i < slotCount; i++) {
 502 Object slotEntries = _variables.get(i);
 503 if (slotEntries != null) {
 504 if (slotEntries instanceof ArrayList) {
 505 ArrayList slotList = (ArrayList) slotEntries;
 506
 507 for (int j = 0; j < slotList.size(); j++) {
 508 allVarsEverDeclared.add(slotList.get(i));
 509 }
 510 } else {
 511 allVarsEverDeclared.add(slotEntries);
 512 }
 513 }
 514 }
====

In Line 508, should the indexer, i, of slotList.get(i) be j as i is the inner loop iterates by slotList.size()? It might be a trivial issue but wanted to report just in case. Thanks!
