This is the main method from the Java Code:

public static void main(String[] args) throws Exception
{
    Server server = new Server(8083);
    WebAppContext webapp = new WebAppContext();
    webapp.setContextPath("/");
    webapp.setWar("C:\\Solr\\solr-4.4.0.war");
    server.setHandler(webapp);
    System.setProperty("solr.solr.home", "C:\\solr");
    server.start();
    server.join();
}

We are using a custom fieldtype declared in the schema.xml like this (it works without this fieldtype):

<fieldType name="zyfield" class="solr.TextField" positionIncrementGap="0" >
<analyzer type="index">
    <!--<tokenizer class="solr.PatternTokenizerFactory" pattern="([\.0-9]+|@??[&amp;'a-zA-Z_0-9-]+(\.(net|ie|uk|com|txt))?)" group="1"/>-->
    <tokenizer class="solr.PatternTokenizerFactory" pattern="(www|@??[-0-9\p{L}\p{Sc}]+?[-'0-9.\p{L}\p{Sc}&amp;]*[-0-9\p{L}]+?|[-0-9\p{L}\p{Sc}]+?)" group="1"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="ie.solrplugin.KDelimiterFilterFactory"/>
    <filter class="ie.solrplugin.JunkTokenFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>
<analyzer type="query">
    <tokenizer class="solr.PatternTokenizerFactory" pattern="(www|@??[-0-9\p{L}\p{Sc}]+?[-'0-9.\p{L}\p{Sc}&amp;]*[-0-9\p{L}]+?|[-0-9\p{L}\p{Sc}]+?)" group="1"/>
    <filter class="solr.LowerCaseFilterFactory"/>
    <filter class="ie.solrplugin.KDelimiterFilterFactory"/>
    <filter class="ie.solrplugin.JunkTokenFilterFactory"/>
    <filter class="solr.ASCIIFoldingFilterFactory"/>
</analyzer>

You are likely hitting a complexity between the classpath of the project running your main method and the classloader isolation present for all WebApps.

Try adding this to tell the WebAppContext to use the parent classloader over the WebApp's own.

public static void main(String[] args) throws Exception
{
    Server server = new Server(8083);
    WebAppContext webapp = new WebAppContext();
    webapp.setContextPath("/");
    webapp.setWar("C:\\Solr\\solr-4.4.0.war");
    webapp.setParentLoaderPriority(true);     // <-- this line
    server.setHandler(webapp);
    System.setProperty("solr.solr.home", "C:\\solr");
    server.start();
    server.join();
}
