Saxon

I run a small XSLT 3.0 stylesheet using SaxonEE9-5-1-6J.

If I install my license key everything is working just fine. But, if NO license key is installed i get the following error:

java.lang.NullPointerException

stack:

com.saxonica.config.ProfessionalConfiguration.loadLicense(ProfessionalConfiguration.java:391)

com.saxonica.config.ProfessionalConfiguration.isLicensedFeature(ProfessionalConfiguration.java:367)

com.saxonica.config.ProfessionalConfiguration.makeStyleNodeFactory(ProfessionalConfiguration.java:504)

net.sf.saxon.PreparedStylesheet.(PreparedStylesheet.java:87)

net.sf.saxon.PreparedStylesheet.compile(PreparedStylesheet.java:113)

net.sf.saxon.s9api.XsltCompiler.compile(XsltCompiler.java:330)

Any ideas why I get a NullPointerException instead of a 'normal' execption? Is this a bug in Saxon?

Here's my Java code:

Configuration configuration = new com.saxonica.config.ProfessionalConfiguration();

Processor processor = new Processor(configuration);

XsltCompiler compiler = processor.newXsltCompiler();

XsltExecutable executable = compiler.compile(...);

Thank you.
