[#2631] - Not possible to use custom query executor: bug in IReportCompiler

It is not possible to execute any custom query.

com.jaspersoft.ireport.designer.compiler.IReportCompiler.run() method contains the following code:
String queryLanguage = "sql";
JasperDesign jd = null;
try {
jd = JRXmlLoader.load(JRXML_FILE_NAME);
if (jd.getQuery() != null &&
jd.getQuery().getText() != null)
{
queryLanguage = jd.getQuery().getText();
}
} catch (Exception ex) { }

// Try to look for a good QueryExecutor...
List<QueryExecuterDef> configuredExecuters = IReportManager.getInstance().getQueryExecuters();
for (QueryExecuterDef qe : configuredExecuters)
{
if (qe.getLanguage().equals( queryLanguage ))
...

getQuery().getText() is called while getQuery().getLanguage() should be called.
