We are injecting a `java.nio.Path` object into some bean as a class field, say `rootPath`. The injected Path object is then used as follows
{code:java}
java.nio.files.Files.createDirectories(rootPath)
{code}
This leads to a `java.nio.file.ProviderMismatchException` when the producer of the path object additionally declares `@ApplicationScoped`. Further debugging shows that in this case the path instance is a WELD proxy: `Comparable$Iterable$Path$Watchable$538699755$Proxy$_$$_WeldClientProxy`.
However, the code works without declaring `@ApplicationScoped` for the producer. In this case the path instance is a `sun.nio.fs.UnixPath` and the statement above does not throw the exception.
This seems to be related to [this question on Stackoverflow|https://stackoverflow.com/q/22611919]. Seems that the proxy somehow interferes with the provider. |
