The JBoss with integrated jetty I`m using creates temporary files (in source code: Handler.java).
One group ends with .tmp and another group is called nested-****.jar.
Both file(type)s are stored in the TEMP-dir (e.g. C:\temp).
Although after creation there is the jdk-function deleteOnExit called, to be sure files will be deleted after/with program shutdown, only file with suffix .tmp are deleted. But the *.jar-files are still there.
I`ve tested my temp-dir with the functionality to create and delete temp files and it works without mattering suffix.
It`s a problem many users before have had, but it seems there is no integrated solution.
May be, anyone has it and read these lines and answer to it.
