Saxon

When the stylesheet is supplied from source code, at Transform#1264 pss.getGlobalContextRequirement() returns null, so buildSourceTree is false; when it is supplied from a SEF file, it returns a non-null GlobalContextRequirement with absentFocus=false, so buildSourceTree is true.

The test case can be fixed by ensuring that PackageLoaderHE.readGlobalContext doesn't create a GlobalContextRequirement in the rebuilt package if there is no <glob/> entry in the SEF file.

It just remains to create a regression test...

Attempting to test this in a JUnit test, verifying that no warnings are output.

This encounters a different problem. If I set an initializer that calls Configuration.setLogger(), then Verifier fails with an NPE trying to display the license message. The license message is sent to config.getStandardErrorOutput(), which is null if a Logger has been set. The implication is that config.setLogger() simply doesn't work. At any rate, the relationship of config.setStandardErrorOutput() and config.setLogger() is complex and poorly explained.

Tried getting around this by making the Logger extend StandardErrorLogger, but that doesn't work either, because the ErrorReporter used by the run-time Controller doesn't use the Logger registered with the Configuration.

So I'm coming to the conclusion that when running from the command line, there's no way to redirect warnings to a destination other than System.err, which makes this test rather hard to write.

I found another way to write the test: register an Initializer which registers a SourceResolver; the SourceResolver detects that the supplied Source is an in-memory document tree rather than a stream. I'll raise a separate bug on the Logger issues.

Bug fix applied in the Saxon 10.3 maintenance release
