Eu instalei uma das mais recentes construções diárias de salamandra picante. Se eu habilitar aplicativos java swing xmir, como o NetBeans ou o Oracle SQL Developer, apenas exiba sua tela inicial, mas eles não são exibidos. Eles não parecem congelar, porque estão corretamente listados na lista de processos. Eu estou usando um chipset da Intel. Mais ainda, mesmo com x fallback jayatana, que na versão anterior do Ubuntu funcionava como esperado mostrando menus de aplicações java na barra de menu global, parou de funcionar com oracle java e open jdk.
Isso é o que eu vejo no log de inicialização do oracle sqldeveloper 4 em execução no OpenJDK Runtime Environment (IcedTea 2.3.12) (7u25-2.3.12-4ubuntu1) OpenJDK VM de servidor de 64 bits (compilação 23.7-b01, modo misto) :
