List.contains() fails to detect element match when input param is an SObject Id field, but succeeds when debug logs with log filter for Apex Code set to FINEST is enabled for the running user.

1) Create below Apex trigger on Lead:

trigger LeadTrigger on Lead (after update) {
// Set<String> lst = new Set<String>(); // Workaround #1
List<String> lst = new List<String>();
lst.add(Id.valueOf('0121U000000iH33QAE')); // make sure this is an actual Lead record type ID

// system.debug(lst); // Workaround #2 (to use if lst's type is List)

for (String leadId : Trigger.newMap.keyset()) {
Lead tmpLead = Trigger.newMap.get(leadId);
String debugMessage = 'Lead\'s record type ID:' + tmpLead.RecordTypeId
+ '; lst.isEmpty(): ' + lst.isEmpty()
+ '; lst.get(1): ' + lst.get(1)
+ '; lst.indexOf(tmpLead.RecordTypeId): ' + lst.indexOf(tmpLead.RecordTypeId)
+ '; lst.contains(tmpLead.RecordTypeId): ' + lst.contains(tmpLead.RecordTypeId);

system.assert(false, debugMessage);

2) Make sure debug logs for your user (if enabled) don't set the Apex Code log filter to FINEST. Instead, use FINER or below.

- By default, the Developer Console sets a trace flag that sets the Apex Code log filter to FINEST.
- You will need to either modify the SFDC_DevConsole Debug Level or close the Developer Console, delete the trace flag created by the Developer Console, and set up debug logs using a custom debug level by leveraging the setup page (Setup | Logs | Debug Logs).

3) Navigate to a Lead record, and try to inline edit it. Assertion will show this:

Lead's record type ID: 0121U000000iH33QAE; lst.isEmpty(): false; lst.get(1): 0121U000000iH33QAE; lst.indexOf(tmpLead.RecordTypeId): -1; lst.contains(tmpLead.RecordTypeId): false: Trigger.LeadTrigger: line 18, column 1

which shows that the list does contain the record type ID, but List.contains(<ID>) is returning false.

Actual result: List.contains() fails to detect SObject's ID.

Expected result: List.contains() should return true.

1) Use Set<String> instead of List<String>

2) If List<String> is used, then make sure to add System.debug(<list-name>); before List.contains() is invoked. Please see Apex trigger above for location of this statement.
