The error is when one uses the value assigned within a synchronized section, outside of a synchronized section. if(x == null) is outside of synchronized section x = new | method(); Very very specific check for double checked locking. author:    CL Gilbert (dnoyeb@users.sourceforge.net) Method Summary public  Object visit(ASTClassOrInterfaceDeclaration node, Object data)      public  Object visit(ASTMethodDeclaration node, Object data)      Method Detail visit public Object visit(ASTClassOrInterfaceDeclaration node, Object data)(Code) visit public Object visit(ASTMethodDeclaration node, Object data)(Code)
