Forwarding to component owner for consideration.

I've ran into this as well, and I get the impression it's plaguing others. I noticed YUI Compressor 2.3.6 and the removal of the old Rhino -- any chance the compressor will get more friendly?

Thanks a lot!

This bug has been fixed in the latest version of compressor. Please download the 2.4 version and give it a try.

The bootstrapping works fine when executing the jar like normal, but I'm calling the compress method directly, like this:
JavaScriptCompressor compressor = new JavaScriptCompressor(in, e_reporter);
compressor.compress(out, -1, false, true, true, false);

I had to add the regular js.jar into the classpath for a new project i'm working on, and now the compressor isn't working properly any more. Any ideas?

There are really 2 issues in this ticket.

1) YUICompressor breaks on o+="rn"
2) YUICompressor requires its own modified Rhino library

1. 1 is bug, and is fixed. #2 is an enhancement request.

Reworking the YUICompressor to work with the standard unmodified Rhino package is a noble goal, but not trivial or easy. Using the compressor from within a Java project is a use-case that would be nice to support, but is not the primary use-case for the yuicompressor. As such, this is not high priority.

Putting on the roadmap for FUTURE.

Hi,

Since Rhino 1.7R3 (out since 2011-05-09), there is now an AST API provided to enable anyone to bridge from internal Rhino parsing.
Maybe it'll be easier for YUICompressor to use this ?

Regards,

FYI, this problem is causing a lot of other projects to have to fork and modify/repackage the YUICompressor code, which means improvements to the otherwise excellent YUICompressor aren't making it out to as many people as they should:

Liferay portal: http://issues.liferay.com/browse/LPS-3169 ("WebLogic chokes on rhino.jar / yuicompressor.jar")
(To resolve, had to repackage YUICompressor and Rhino code)

Thank you for your bug report. We are deprecating YUI Compressor in favor of yuglify. Please see our announcement for more information: http://www.yuiblog.com/blog/2012/10/16/state-of-yui-compressor/. We will consider migrating these legacy tickets to GitHub if there are community maintainers willing to step up and own them.
