I wanted to read some mail, but that produces some exception:

<html>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

If i delete the <meta http-equiv="Content-Type" content="text/html;
charset=iso-8859-1"> line, everything works fine.

possible solution but a little bit nasty. Basically it ignores HTML meta
content-type tags and uses only message headers.

After reading the documentation and talking with some people about this,
JEditorPane will always throw an exception when hitting a meta tag even if the
character encoding type is correct so this might be the only solution.

Summary: Reading mail produces exception → Reading mail with charset in HTML meta tag produces exception
This is a Swing issue, not a Grendel issue.
The stack trace should be provided to Sun as this is a Swing bug, not a Grendel bug; i.e., Swing should 
handle unrecognized tags better than this.

I was reading a number of newsgroup posts about this, and it is the expected
action. You'll notice that it won't be thrown in cases where the URL is directly
read. This workaround works just fine though because it overrides sun's logic
and is appropriate in most cases but not in this one.

And it does recognize the tag. That's not the issue here. It's about the charset
changing because of a tag. I have a feeling that issues like this is why HTML
was disabled in Grendel before I re-enabled it.
