OpenOn on JSP tags works wrongly if project contains many jars with the same name

If project contains many jars with the same taglib and the same name OpenOn on JSP tags show one line for each jar. But every OpenOn menu items opens the same taglib from the same jar

Test case:
1. Create JSF KickStart Project
2. Create WebContent/WEB-INF/lib2 folder
3. Copy jsf-tlds.jar from WebContent/WEB-INF/lib to WebContent/WEB-INF/lib2
4. Open hello.jsp in Visual Page Editor
5. Point mouse to f:view tag then press Ctrl key
ASSERT: OpenOn windows appears
6. Select first item 'jsf-tlds.jar : jsf_core.tld : view'
ASSERT: JBoss Tools Tag Library Editor appears for jsf-tlds.jar from WebContent/WEB-INF/lib folder
7. Select second item 'jsf-tlds.jar : jsf_core.tld : view'
FAIL: JBoss Tools Tag Library Editor appears for jsf-tlds.jar from WebContent/WEB-INF/lib folder
