Description
There are a few SuppressWarnings statements in the test lib that could be cleaned up. Furthermore, in jdk/test/lib/process/StreamPumper.java, the printing of IOException stack traces when the input stream is simply closed causes quite some noise, e.g. dozens of java.io.IOException: Stream closed at java.base/java.io.BufferedInputStream.getBufIfOpen(BufferedInputStream.java:169) at java.base/java.io.BufferedInputStream.read(BufferedInputStream.java:335) at java.base/java.io.BufferedInputStream.fill(BufferedInputStream.java:245) at java.base/java.io.BufferedInputStream.read1(BufferedInputStream.java:285) at java.base/java.io.BufferedInputStream.read(BufferedInputStream.java:344) at java.base/java.io.FilterInputStream.read(FilterInputStream.java:107) at jdk.test.lib.process.StreamPumper.run(StreamPumper.java:109) at java.base/java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:515) at java.base/java.util.concurrent.FutureTask.run(FutureTask.java:264) at java.base/java.lang.Thread.run(Thread.java:830) in sun/tools/jcmd/TestProcessHelper which don't help.
