Hello,
Could you please approve straight backport the bug fix in JDK8 to JDK9?
Approved.
Thanks,
Alexandr.
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.*
