The system property 'java.io.tmpdir' gives the name of default temporary-file 
directory. Under solaris (jdk1.3.1-b08, jdk1.4.0-b40) and windows 
(jdk1.3.1-b08, jdk1.4.0-b40) value of this property ends with 
system-dependent default name-separator character. But under linux
(jdk1.3.1-b08, jdk1.4.0-b40) the value does not contain trailing
name-separator.

    JCK1.3a test api/java_io/File/OtherMethodsTests.html#createTempFile fails 
due to this problem on:
        * linux jdk1.3.1-b08
        * linux jdk1.4.0-b40

    The following sample code and output show the problem.

    public static void main(String args[]) {
        System.out.println(System.getProperty("java.io.tmpdir"));

Adding the Slash to /tmp/ under Linux doesn't do any harm, it allows however Solaris Java applications run unmodified under Linux. This is important for  customer .

N/A

Not a bug.  Nowhere is it specified that the value of the system property
java.io.tmpdir should or should not end with a pathname separator.  As noted
in the specification of java.io.File.createTempFile, the value of this property
is system-dependent.  The JCK should be testing the createTempFile method,
not the specific value of this property.

This is still not a JCK-related bug.  If a specific customer needs this to be
changed then please submit a separate RFE and escalate it.

Note that a workaround does exist: Simply set java.io.tmpdir on the command
line to whatever is required.
