Bug 6478 Jar packager progress messages misleading
When exporting classes to a JAR file, the progress message says things like: "Exporting org.eclipse.foo.MyFile.java" This is misleading, because it looks like it's adding .java files to the zip, but it's actually adding class files. I actually canceled the export and went to check the jar file when I saw these messages. I suggest just trimming the .java suffix: "Exporting org.eclipse.foo.MyFile"
