运行yuicompressor时出现Java错误

Question

I'm running the YUI compressor jar fine on my local dev server, but on the web server I'm getting this error:

Fatal error: Uncaught exception 'Assetic\Exception\FilterException' 
with message 'An error occurred while running:

I already checked with the server support, and they said to contact the developers. Any clue as to what this might be? I've also posted on Github, but no luck.

This is the Java version:

# java -version
java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06)
Java HotSpot(TM) Server VM (build 20.12-b01, mixed mode)

See this similar thread or this discussion - basically, you should contact your server support to change their java runtime environment to be something proper instead of GCJ. Using a regular JDK would solve this.

If they insist on using GCJ, they at least need to fix it to be runnable.
