Java – why does my jdialogs leak?

I have a JFrame from which I open a jdialog and another jdialog – menas from the dialog. I have three windows visible (JFrame, jdialog1, jdialog2)

When I close both dialog boxes and run the garbage collector several times (from NetBeans Profiler), I can see that jdialog2 (the one opened from jdialog1) is garbage collection, but jdialog1 (opened from JFrame) is still hung in the active object pool

Every time I create a new object - so after a while I have an outofmemoryerror Doue to a memory leak

Do I have to deal with jdialogs in a special way to avoid leakage?

By the way, I do setdefaultcloseoperation (jdialog. Dispose_on_close) on two dialog boxes,

Solution

To release the allocated resources, you must call the dispose method It is not enough to just hide the dialog box
