>            Reporter: Martin Häusler

> Most of the tests in StructureStandardTestSuite/IoGraphTest cause an unexpected java.io.IOException. The stack trace looks like this:
> {panel:title=Stack Trace}
> java.io.IOException: The the file name, directory name or volume label syntax is incorrect.
> 	at java.io.WinNTFileSystem.createFileExclusively(Native Method)
> 	at java.io.File.createTempFile(Unknown Source)
> 	at org.apache.tinkerpop.gremlin.TestHelper.generateTempFile(TestHelper.java:74)

> I'm running the test suite from Eclipse under Java 8, on a Windows 10 x64 machine. The dependencies in my project are managed with gradle. Investigating the offinsive line (org.apache.tinkerpop.gremlin.TestHelper.java@74) in the debugger reveals the following parameters of "File.createTempFile(...)":
> {noformat}
> fileName = "shouldReadWriteModernToFileWithHelpers[graphml]"
> fileNameSuffix = ".xml"
> path = "file:\D:\guh\caches\modules-2\files-2.1\org.apache.tinkerpop\gremlin-test\3.0.2-incubating\345ec87b74923b76374111f2e4040d4d105f256\temp"
> {noformat}
> The offensive part is the "path" variable, because it contains the prefix "file:\". I tried the same thing in a dedicated JUnit test without the prefix and it works fine.
> I would be very happy to see this issue fixed, as this considerably reduces the amount of tests in the suite that I can run against my graph implementation.
