Re: [Ikvm-developers] problems finding files when calling assembly is not the entry assembly

[Jeroen F. <je...@su...>]

In https://github.com/plutext/docx4j/blob/master/src/main/java/org/docx4j/utils/ResourceUtils.java you can see that docx4j uses the thread context class loader to load its own resources and IMO that is wrong. It should use its own class loader to load its own resources.

There are two workarounds:
1) Do a Thread.currentThread().setContextClassLoader(null); so that docx4j falls back to a hack it apparently added for an older IKVM version.
2) Use ikvm.runtime.Startup.addBootClassPathAssembly() to add the assembly to the "boot classpath" so that it is visible from the default thread context class loader.

Jeroen
