There has been much hubbub about the LGPL beging viral for Java code because of how it links. The GNU Classpath project had this very issue and this is why they changed their license to the GPL with the following exception:
As a special exception, the copyright holders of this library give you permission to link this library with independent modules to produce an executable, regardless of the license terms of these independent modules, and to copy and distribute the resulting executable under terms of your choice, provided that you also meet, for each linked independent module, the terms and conditions of the license of that module. An independent module is a module which is not derived from or based on this library. If you modify this library, you may extend this exception to your version of the library, but you are not obligated to do so. If you do not wish to do so, delete this exception statement from your version.
I suggest that this should be the standard GPL license for any Java project when you intend it not to be viral.
