JNDI resource opened but not safely closed

Reports JNDI resources that are not safely closed. JNDI resources reported by this inspection include javax.naming.InitialContext, and javax.naming.NamingEnumeration.

By default, the inspection assumes that the resources can be closed by any method with 'close' or 'cleanup' in its name.

Example:

  Object findObject(Properties properties, String name) throws NamingException {
    Context context = new InitialContext(properties); //context is not closed
    return context.lookup(name);
  }

Locating this inspection

By ID

Can be used to locate inspection in e.g. Qodana configuration files, where you can quickly enable or disable it, or adjust its settings.

JNDIResourceOpenedButNotSafelyClosed

Via Settings dialog

Path to the inspection settings via IntelliJ Platform IDE Settings dialog, when you need to adjust inspection settings directly from your IDE.

Settings or Preferences | Editor | Inspections | Java | Resource management

Use the following options to configure the inspection:

Whether a JNDI Resource is allowed to be opened inside a try block. This style is less desirable because it is more verbose than opening a resource in front of a try block.
Whether the resource can be closed by any method call with the resource passed as argument.
