java class objectId() overrides .object_id
------------------------------------------
Key: JRUBY-5090
URL: http://jira.codehaus.org/browse/JRUBY-5090
Project: JRuby
Issue Type: Bug
Components: Java Integration
Affects Versions: JRuby 1.5
Reporter: Xore Ander
I have a java class which inherits the static method objectId() from
http://commons.apache.org/logging/apidocs/org/apache/commons/logging/impl/LogFactory.html
When I migrated my codebase from jruby 1.4 to 1.5, my app started breaking
because a const_missing call ended up dying in
activesupport/.../introspection.rb where it was polling .object_id of a variety
of constants. It seems that the wrapper for SomeJavaClass maps .object_id to
SomeJavaClass.objectId(arg1), and was dying in a 0 for 1 argument error.
JavaUtil.getRubyCasedName(...) seems to be involved, however, i believe i
tracked down the core issue here:
http://github.com/jruby/jruby/commit/7c4139b5eb12ac5794b79a20fe37e8f2877d6da4
in
- RESERVED_NAMES.put("object_id", new AssignedName("object_id",
Priority.RESERVED));
It's not clear to me why "object_id" would be removed from RESERVED_NAMES but
"__id__" was not. Was this change made in error? Should object_id have been
added to STATIC_RESERVED_NAMES and/or INSTANCE_RESERVED_NAMES? (my case deals
with STATIC, but I can see this affecting INSTANCEs as well)
I fixed the regression locally by reverting the one line of the change
+ RESERVED_NAMES.put("object_id", new AssignedName("object_id",
Priority.RESERVED));
