Hello,
Could you please approve straight backport the bug fix in JDK8 to JDK9?
Bug Description:
In Component/Container/JComponent's AccessibleContext inner classes, a
private variable propertyListenersCount is used to make sure a specific
listener is only added once through addPropertyChangeListener. However,
ContainerListener which declared in Container's inner class was added to
PropertyChangeListener in both Container and it's child class,*in case
of nested levels us*ed,* exponential listeners will be adde*d and lead
to performance issue*. *
***
**Fix Description:
The fix removed code in AccessibleJComponent(Inner class of JComponent*)
which *add*ing *listener**declared *and*added as property change
listener through parent class. This way, the listener won't be added
twice and lead to exponential listeners added in nested levels case.*
