It utilizes a name shared memory mechanism, identified 41266733Speterby a backing store file in the file system name space. The location of 42266733Speterthe backing store file is platform specific and is dictated primarily by 43266733Speterthe JVM implementation. However, the <code>java.io.tmpdir</code> system 44266733Speterproperty generally contains the location of the files, with the exception 45266733Speterof the Solaris implementation, as the SDK and HotSpot JVM use different 46266733Speterlocations for their temporary file storage. The HotSpot JVM uses the 47266733Speter<em>/tmp</em> directory and the SDK uses <em>/var/tmp</em>. The classes 48266733Speterin this specifically use <em>/tmp</em> when running on Solaris. 49266733Speter</body> 50266733Speter</html> 51266733Speter
