加载JasperPrint文件时JasperReports非常慢

Question

I'm loading JasperPrint file and it's taking about 2 seconds to load a 60KB file.

String jpXML = .....;
InputStream is = new ByteArrayInputStream(jpXML.getBytes("UTF-8"));
JasperPrint jp2 = JRPrintXmlLoader.load(is); //This is taking 2 seconds

Does anybody know how to speedup this? The problem seems to be in the XML Digester...

Thanks.

PROBLEM SOLVED!!

The JasperPrint load felt from 2000 miliseconds to 10 miliseconds.

I've just updated this dependency from:

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.10.0</version>
</dependency>

To

<dependency>
    <groupId>xerces</groupId>
    <artifactId>xercesImpl</artifactId>
    <version>2.11.0</version>
</dependency>

So there might be some performance issue with the version 2.10.0 of this lib.
