StringIndexOutOfBoundsException when parsing a specific Wikipedia Page

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run DataMachine to populate the wikipedia database; using the dump from 
2011-11-15
2. Attempt to get the parsed textual content from the article on Conditional 
Comment like this:

Page page = wiki.getPage("Conditional_comment");
ParsedPage parsedPage = page.getParsedPage();
System.out.println(parsedPage.getText());

What is the expected output? What do you see instead?
I expect to see the Wiki markup converted into plain text. Instead I see an 
exception:

Exception in thread "main" java.lang.StringIndexOutOfBoundsException: String 
index out of range: -1
    at java.lang.AbstractStringBuilder.substring(Unknown Source)
    at java.lang.StringBuilder.substring(Unknown Source)
    at de.tudarmstadt.ukp.wikipedia.parser.mediawiki.SpanManager.substring(SpanManager.java:155)
    at de.tudarmstadt.ukp.wikipedia.parser.mediawiki.ModularParser.parseSpecifiedTag(ModularParser.java:898)
    at de.tudarmstadt.ukp.wikipedia.parser.mediawiki.ModularParser.parseSpecifiedTag(ModularParser.java:862)
    at de.tudarmstadt.ukp.wikipedia.parser.mediawiki.ModularParser.parse(ModularParser.java:356)
What version of the product are you using? On what operating system?

Please provide any additional information below.
I have attached a modification of the Demo program; it contains the Wiki markup 
of the page in question. You can run this program; it exhibits the same 
behavior.

This issue is fixed in the current SNAPSHOT version (0.8.0-SNAPSHOT). 
I plan to make a new release soon.
If you need the new version urgently, you can check it out an build it on your 
own. If that's not an option, I could also send you a jar.

I just created the JWPL 0.8.0 release.
This should solve your problems.
