jdk8 hs Windows com/sun/jdi tests fail in ShellScaffold.sh: C:\Windows/tmp.6102: Permission denied

[andrew-m-leonard]

This test also fails on zLinux for a different problem here: https://github.com/AdoptOpenJDK/openjdk-tests/issues/2408

The ShellScaffold.sh script tries to create a tmp file using the wrong slashes for CYGWIN environment: https://github.com/AdoptOpenJDK/openjdk-jdk8u/blob/a1d853a5d797f38f7be8c260f4a83c1b3fe48adc/jdk/test/com/sun/jdi/ShellScaffold.sh#L271

causing:

The logic needs to use correct slashes depending on Windows or Cygwin.

The ShellScaffold.sh usage of a tmpFile here: https://github.com/AdoptOpenJDK/openjdk-jdk8u/blob/a1d853a5d797f38f7be8c260f4a83c1b3fe48adc/jdk/test/com/sun/jdi/ShellScaffold.sh#L270 Probably needs changing to do something more like this example here for Windows/Cygwin: https://github.com/AdoptOpenJDK/openjdk-jdk8u/blob/a1d853a5d797f38f7be8c260f4a83c1b3fe48adc/jdk/test/javax/imageio/spi/AppletContextTest/BadPluginConfigurationTest.sh#L96 and use the TMP location to create the tmpFile...
