Description
solver.solve() throws an exception when configured with a KieBase that was built using calls to KieFileSystem.write(String path, String content) where path contains the \ character.
Exception in thread "main" java.lang.RuntimeException: Unexpected global [scoreHolder]

The same issue may be experienced with any of the versions of write that take a "path" parameter but I haven't tried them myself.
No error or exception is produced by the call to KieFileSystem.write(...) itself.
When a KieBuilder.buildAll() is called a warning is logged:
[o.d.compiler.kie.builder.impl.AbstractKieModule ] No files found for KieBase defaultKieBase
Other than this log entry there is no indication of a problem until the exception is thrown when calling solver.solve()
