QPID-8744: [Broker-J] Jackson ObjectMapper instances shouldn't be created on

> Key: QPID-8744
> URL: https://issues.apache.org/jira/browse/QPID-8744
> Project: Qpid
> Issue Type: Improvement
> Components: Broker-J
> Affects Versions: qpid-java-broker-10.0.1
> Reporter: Daniil Kirilyuk
> Priority: Minor
> Fix For: qpid-java-broker-10.0.2

>
> Jackson ObjectMapper is thread-safe for both reads and writes once
> constructed, but relatively expensive to create. The codebase has several
> locations where new ObjectMapper() is called per method invocation. These
> should be replaced to private static final fields.
> Main affected classes are:
> # AttributeValueConverter
> # RestServlet
> # QueryServlet
> # ManagementInputConverter
> # ConfiguredObjectBinding
> # ReplicatedEnvironmentFacade
> # AbstractJDBCConfigurationStore
> # AbstractJDBCPreferenceStore
> # HttpManagement
> # UpgradeFrom7to8
