Question

When minimising yui with 2.4.6, I get this problem:

java.lang.StringIndexOutOfBoundsException: String index out of range: 232

at java.lang.String.substring(String.java:1934)
at com.yahoo.platform.yui.compressor.JavaScriptCompressor.printSourceString(JavaScriptCompressor.java:267)
at com.yahoo.platform.yui.compressor.JavaScriptCompressor.parse(JavaScriptCompressor.java:330)
at com.yahoo.platform.yui.compressor.JavaScriptCompressor.<init>(JavaScriptCompressor.java:533)

It works when started through my IDE but when deployed to jboss it doesn’t. This place: http://yuilibrary.com/forum/viewtopic.php?p=20086 has some discussion of the same problem.

Apparently the issue is around org/mozilla/javascript/Parser being in the two jars that are pulled in from my maven config:

<dependency>
<groupId>com.yahoo.platform.yui</groupId>
<artifactId>yuicompressor</artifactId>
<version>2.4.6</version>
</dependency>

Is there any way I can solve this using maven exclusions etc. or by upgrading my version of YUI. It seems daft that it just doesn’t work and I don’t want to have to write a custom classloader.

Please help!

I solved this problem by repackaging yuicompressor myself to include most of the rhino source. See my reply to Howard M. Lewis Ship.

The repackaged source can be found here : http://viscri.co.uk/labs/tapestry/yuicompressor-rhino-bugfix-5.0.jar. Just add this to your pom:

<dependency>
   <groupId>yuicompressorbugfix</groupId>
   <artifactId>yuicompressor-rhino-bugfix</artifactId>
   <version>5.0</version>
</dependency>

If you don’t run your own version of nexus, you’ll have to install it on the machine that you want to build on. This is the command you need I think: http://maven.apache.org/guides/mini/guide-3rd-party-jars-local.html

You’ll also need to exclude the yuicompressor version that tapestry pulls in:

<dependency>
   <groupId>org.apache.tapestry</groupId>
   <artifactId>tapestry-yuicompressor</artifactId>
   <version>5.3.2</version>
   <exclusions>
       <exclusion>
             <groupId>com.yahoo.platform.yui</groupId>
             <artifactId>yuicompressor</artifactId>
       </exclusion>
   </exclusions>

This should work.
