since 2006 I am using eclipse on and off, I am using intellij more in work but I dont have license for home so I decided to check eclipse back. I am trying to write some aspectj and installed the editor to latest eclipse and exception is
"AJCompilationUnit tried to access private field org.eclipse.jdt.internal.core.JavaElement.parent (org.eclipse.ajdt.core.javaelements.AJCompilationUnit is in unnamed module of loader "
decided to get latest from https://github.com/eclipse/org.aspectj/blob/master/docs/developer/IDE.md#eclipse
and finally aj editor works
