commit 67ca09b16051e97e725752630a576e17e2f701a4
Author: Federico Mariani <[email protected]>
AuthorDate: Thu Nov 5 12:12:59 2026 +0100

    CAMEL-26415: camel-micrometer-starter - test 
camel.metrics.record-last-exchange-timestamp (#2072)
    
    #2069 added the property without a test. The two tests check that the
    camel.exchanges.last.timestamp gauge is registered by default and is not
    registered with camel.metrics.record-last-exchange-timestamp=false.
