--------------------------------
Summary: Potential null pointer reference in
ConfigCommand#execute()
Key: ACCUMULO-2738
URL: https://issues.apache.org/jira/browse/ACCUMULO-2738
Project: Accumulo
Issue Type: Bug
Reporter: Ted Yu
Priority: Minor
Starting at line 210 :
{code}
if (dfault != null && key.toLowerCase().contains("password")) {
siteVal = sysVal = dfault = curVal = curVal.replaceAll(".", "*");
}
if (sysVal != null) {
if (defaults.containsKey(key) &&
!Property.getPropertyByKey(key).isExperimental()) {
printConfLine(output, "default", key, dfault);
{code}
Comparing dfault with null implies that dfault may be null.
If that is the case, we would get null pointer dereference in the call to
printConfLine() at line 215 where dfault.replace() is called.
