06/12/2018, 2:26 PM@edvin I am trying to use
with a class which is loaded using a child classloader. But I am gettingimportStyleSheet
. My di container is able to load the class and create object out of it, but onlyjava.lang.ClassNotFoundException
is not able to use it when I pass the class.importStyleSheet - a

06/12/2018, 2:27 PMhere is the stacktrace - a

06/12/2018, 2:27 PM@anidotnet uploaded a file: ClassNotFoundException for importStyleSheet - a

06/12/2018, 2:28 PMAny idea how to use stylesheet class loaded from a different classloader? - c

06/12/2018, 3:42 PMExtending urlclassloader.. It is just a plugin class loader - c
carlw
06/12/2018, 3:55 PMmaybe try a classloader like this? URLClassLoader cl = new URLClassLoader( someURLs, Thread.currentThread().getContextClassLoader() ); - a
anidotnet
06/12/2018, 5:51 PMThis is my classloader - a
anidotnet
06/12/2018, 5:53 PMBut if I use
would not it create problems if I invoke my plugin from different thread?Thread.currentThread().getContextClassLoader() - a

06/12/2018, 7:55 PMCan someone help demystify for me how weak listeners work? I know they help prevent memory leaks, but it caused my utilities to completely stop binding and I had to resort to plain listeners, as shown in this diff. - t

06/12/2018, 7:55 PMdoes this seem familiar? - c

06/12/2018, 7:56 PMit's not TFX and old but it still applies - t

06/12/2018, 7:58 PM@carlw this looks exactly like my issue. - t

carlw
06/12/2018, 8:00 PMcan you make the change listener a member variable? - t
thomasnield
06/12/2018, 8:00 PM@carlw I was just thinking about that. So like this? .... - t

06/12/2018, 8:03 PMDo I need to remove it on
or something as well?finalize() - t
thomasnield
06/12/2018, 8:05 PM@carlw Or do I wrap it up in a weak listener again 🤔 - c
carlw
06/12/2018, 8:05 PMi wrapped mine up in the weak listener. weak listener is giving a cue to the runtime so that one side will balk if two people are trying to reclaim a reference - c
carlw
06/12/2018, 8:06 PMso, it's not like malloc / free where you'd need something deliberate put in a finalize() - c
carlw
06/12/2018, 8:06 PMthe way to see if you have a problem is when a bunch of those objects show up unclaimed in jvisualvm - c
