[#2633] - Folder ending in ".jar" in classpath doesn't work

I added a folder from an exploded java ee enterprise archive deployment EJB module - ie app.ear/app.jar/ to the classpath of ireport and found that it was not loaded.
I tracked the problem down to ReportClassLoader.java

boolean isJar(String pathEntry) {
return pathEntry.toLowerCase().endsWith(".jar") || pathEntry.toLowerCase().endsWith(".zip");
}

and I changed it to

boolean isJar(String pathEntry) {
File file = new File(pathEntry);
return (file != null && ! file.isDirectory()) && (pathEntry.toLowerCase().endsWith(".jar") || pathEntry.toLowerCase().endsWith(".zip"));
}

Could you please consider this change for the next release?
