Memory leak when using Jersey with HK2

[albanf]

When using Jersey and Jackson to deserialize XML, any change to the configuration of the WebTarget causes a memory leak since hk2 3.0.4 (and up to 3.1.1).

I suspect this is caused by this change in HK2: eclipse-ee4j/glassfish-hk2@9e5b5f5 (FISH-6432 Applications Take Longer To Deploy on JDK 17) since the same occurs with the patched Payara version 3.0.1.payara-p2 (payara/patched-src-hk2@3.0.1.payara-p1...3.0.1.payara-p2).

Not sure if this is a regression in HK2 or something that Jersey is doing incorrectly.

I've tested with Jersey version 3.0.0 to 3.1.9, and the behavior is the same.
