Reload4j doesnot have this package org.apache.log4j.lf5.viewer.categoryexplorer

[sheenamo]

Hi,

Currently I have updated my project from log4j 1.7 to reload4j1.9
everything works fine but one functionality breaks
Exception in thread "AWT-EventQueue-2" java.lang.NoClassDefFoundError: org/apache/log4j/lf5/viewer/categoryexplorer/TreeModelAdapter

I have checked and found that reload doesn't contain this package
Any help will be appreciated

More LF5 resources that were left in the dist were removed in 1.2.20
see commit f8f3382

If you were relying on those classes in your dev/confiugration

• your best move is to get rid of them in your dev/configuration
• otherwise you need to reintroduce them by yourself for your need... Beware of potential security implication

If you were not using those classes, test the 1.2.20 in case the exception occured due ton automatic configuration from resources that were left.
