O JDeveloper 11.1.1.6 não trabalha muito bem com o subversion 1.7, pois essa versão não cria uma pasta .svn para cada subpasta e fica apenas um .svn na raiz. Ao executar algumas operações recebi o seguinte erro:

Para que o JDeveloper pudesse trabalhar adequadamente, foi necessário desabilitar o subversion do JDeveloper. Para isso, acesse o menu Versioning, Configure e desmarque o checkbox com o suporte ao subversion.
Clique em OK e Reinicie o JDeveloper. Com isso o erro irá desaparecer!
