Compile fails without "optional" annotations @max_string_length and @max_repeated_length in .proto file #51

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Repro:
1. Generate a .proto file that has a string type but does not have the 
@max_string_length comment
2. Attempt to compile the .proto file

Expected:
I expected it to compile. Instead I get this exception:

This is running 1.0M4 on Java 1.6.0_65 on Max OSX 10.6.

When I add the //@max_string_length=32 annotation it compiles without issue.

A similar exception happens when the //@max_repeated_length annotation is 
missing and you declare an element repeated.
