File not found: for xsd and xsl references in ladybug tree 10.1.0-20260318.042325

[jjansenvr]

The adapter finds the xsd's and xsl's but the ladybug cannot find and display them

[mhdirkse]

Do you have a project for which this happens?

[jjansenvr]

If I roll back to ff.version=9.4.1-20260204.012729 it is not a problem

Similar issues here in 10.x:

When an XsltPipe is defined inside a configuration that uses DirectoryClassLoader, the Ladybug debugger shows "File not found: " for the stylesheet checkpoint, even though the pipe itself executes successfully at runtime.

The XsltPipe resolves styleSheetName through the issuing configuration's own classloader (the DirectoryClassLoader child), which correctly locates the file under the configuration's root directory. The Ladybug backend resolves the same path through the application root classloader, which does not delegate to per-configuration child classloaders. As a result, any resource that lives exclusively in a DirectoryClassLoader-mounted directory is invisible to the Ladybug's file resolver.

Suggested fix

When resolving a stylesheet path for display in the Ladybug, use the classloader of the configuration that owns the pipe (available via the pipe's ApplicationContext), rather than the application root classloader (or whatever is currently used).

I'll need to add some tests for this, but for now this will fix it.
