I am encountering a persistent problem when obfuscating java8 source code. Lambda method references seem to fail at runtime when they are used multiple times within a function. The failing code:
Set<String> roleNames = this.userDAO.getUserRoles(userDTO.getId()).stream().map(RoleDTO::getName).collect(Collectors.toSet());
SimpleAuthorizationInfo authorizationInfo = new SimpleAuthorizationInfo(roleNames);
Set<String> permissions = this.userDAO.getUserPermissions(userDTO.getId()).stream().map(NameDescriptionDTO::getName).collect(Collectors.toSet());
authorizationInfo.addStringPermissions(permissions);
This works fine when compiling with maven and java 8.0_40, however this fails when proguard has obfuscated the lib with the following stack trace:
org.jboss.weld.interceptor.proxy.InterceptorException: java.lang.BootstrapMethodError: call site initialization exception
