Description

The indentation of debug log output by `CodeGenerator` is weird.
The first line of the generated code should be put on the next line of the first line of the log message.

16/03/28 11:10:24 DEBUG CodeGenerator: /* 001 */                                                                                                              
/* 002 */ public java.lang.Object generate(Object[] references) {
/* 003 */   return new SpecificSafeProjection(references); 
...

After this patch is applied, we get debug log like as follows.

16/03/28 10:45:50 DEBUG CodeGenerator:                                                 
/* 001 */ 
/* 002 */ public java.lang.Object generate(Object[] references) {
/* 003 */   return new SpecificSafeProjection(references);
...
