--------------------------------------

             Summary: VirtualSelectorCacheBrokerPlugin throws false positive exception
                 Key: AMQ-8117
                 URL: https://issues.apache.org/jira/browse/AMQ-8117
             Project: ActiveMQ
          Issue Type: Bug
          Components: Broker
    Affects Versions: 5.15.14, 5.15.13, 5.15.12, 5.16.0
            Reporter: Joost van Crugten
         Attachments: activemq.xml, file.data, image-2021-01-07-09-36-50-044.png

Dear,

The VirtualSelectorCacheBrokerPlugin throws an error in the following method:

 
{code:java}
if (!(desc.getName().equals("java.lang.String") || desc.getName().startsWith("java.util."))) {
 throw new InvalidClassException("Unauthorized deserialization attempt", desc.getName());
 }
{code}
This exception is thrown because there are some lines in the selector cache file that do not match the given "startsWith("java.util.")". The code will throw an exception because of the "[L" prefix in front of some java.util. elements in the file:

!image-2021-01-07-09-36-50-044.png!

My activemq.xml and file.data are attached to this ticket.

The selector cache is working fine if I use ActiveMQ version 5.15.11 or below.

I have tried to add jdk.serialFilters for the Concurrent Hashmap, like:

wrapper.java.additional.13=-Djdk.serialFilter=java.util.** (wrapper.conf) and also tried to add this to the java security file, but that did not work.

I hope this issue can be fixed or if it is not a bug, the documentation can be complemented with some notes on how to configure this filters the right way.

Best regards,

Joost
