Expected behavior XML should have only proper configuration

Additional context Add any other context about the problem here.

[naseer-nv]

Reduced the XML size to allow the bug to go through but the issue is apparent from the XML

[idodeclare]

We missed that this broke in b13c5a0e, since at the time OpenGrok configuration-related serialization had already been afflicted by OpenJDK issue, "Unstable behavior of java.beans.XMLEncoder since Java 9".

Interestingly, it seems there's now a workaround documented in "Unstable behavior of java.beans.XMLEncoder since Java 9". So probably both issues could be fixed together.

[vladak]

Another reason for using different serialization scheme for configuration (#2329).
