Description

If you compile jruby 0.9.8 using Java 1.5 or 1.6, you get the following error:

[javac] 124. ERROR in /var/tmp/portage/dev-java/jruby-0.9.8/work/jruby-0.9.8/src/org/jruby/charset/PlainCharset.java
[javac] (at line 10)
[javac] public class PlainCharset extends Charset {
[javac] ^^^^^^^^^^^^
[javac] The type PlainCharset must implement the inherited abstract method Comparable.compareTo(Object)
[javac] ----------

Building with Java 1.4 builds it without issue.

This is actually an Eclipse compiler bug we haven't found a way around yet...Sun's javac compiles this on Java 5 and 6 without problems, as does NetBeans.

I don't know if anyone's tried to follow up with Eclipse or not.

You're right, this works fine with javac. Sorry for not trying that first.

It is worth noting that this also occurs when compiling jikes, if that is any consolation.

In any event, this should be followed up with Eclipse if it hasn't been already. I would volunteer to do it myself, but I doubt I would be able to as accurately describe what we're seeing here.

How did you resolve this? Is there a specific patch to address it I could use?

I resolved this issue by removing the PlainCharset class itself. I realized we doesn't need it.
