YAML short-hand hashes cause the parser to crash
------------------------------------------------
Key: JRUBY-1911
URL: http://jira.codehaus.org/browse/JRUBY-1911
Project: JRuby
Issue Type: Bug
Affects Versions: JRuby 1.0.3
Environment: OS 10.5.2, Mac Mini CD
Reporter: Julian Raschke
Assignee: Thomas E Enebo
The MRI YAML library understands the following syntax:
{{
>> require 'yaml'; YAML.load("foo: { bar }")
=> {"foo"=>{"bar"=>nil}}
}}
Whereas in jruby, it causes a NullPointerException:
{{
irb(main):002:0> require 'yaml'; YAML.parse("foo: { bar }")
NativeException: java.lang.NullPointerException: null
from BaseConstructorImpl.java:150:in
`org.jvyamlb.BaseConstructorImpl.constructObject'
from BaseConstructorImpl.java:289:in
`org.jvyamlb.BaseConstructorImpl.constructMapping'
from JRubyConstructor.java:147:in
`org.jruby.yaml.JRubyConstructor.constructRubyMapping'
...
}}
I couldn't find out whether this is valid YAML or not, but I found it
documented on a Ruby-ish site, so I happily used it a lot, and can't quickly
work around this. I think even if it is not valid YAML, it should be fixed for
consistency with the MRI library.
