Windows network UNC paths not treated correctly (File2/tempPrefix)

Dear all,

We are using Camel's File2 endpoint to deliver reports to a Windows network share. The used URI is (here in a properties file):

# File URI equivalent of \\FILESERVER.mycompany.local\Public\reports
report.delivery.to=file:////FILESERVER.mycompany.local/Public/reports?keepLastModified=true&tempPrefix=tmp_

This results in an exception, see the stack trace (attached).

I debugged and traced the issue back to:

org.apache.camel.component.file.GenericFileProducer#createTempFileName

which is using

org.apache.camel.util.FileUtil#compactPath(java.lang.String, java.lang.String)

This method only preserves the first slash/backslash at the start. For UNC paths on Windows however, 2 backslashes are needed.

I prepared a patch for:

• org.apache.camel.util.FileUtil
• org.apache.camel.util.FileUtilTest

which remedies the issue on Windows.

I would appreciate if you could check the patch, and integrate it to 2.x and 3.x branches if it is ok.

Thank you.

Kind regards,

Clemens
