Description
`jcmd Compiler.perfmap` uses the hard-coded file name for a perf map: `/tmp/perf-%d.map`. We collect profiling data on one system and process it on another system. For long running applications we can create multiple perf map files.
We want to control where  `Compiler.perfmap` creates a perf map by providing a file name as an argument to it.
