RFR JDK-8175288: [TESTBUG] sun/tools/jcmd/TestJcmdDefaults.java failed to parse output of other java process

[harold seigel]

Hi,

Please review this JDK-10 fix for test 
sun/tools/jcmd/TestJcmdDefaults.java.  The test gets a list of Java 
processes and tries to match them to a regular expression. But the match 
fails if the name of one of the Java processes contains a line terminator.

The fix adds "(?s)" to the regular expression used by the test. The 
"(?s)" enables dotall mode, meaning the "." in the test's regular 
expression accepts any characters including line terminators.

The change was regression tested on Linux, macOS X, Solaris, and Windows 
using RDB.  The modified regular expression was tested using a small 
Java program that was fed command lines similar to the one that caused 
the test to fail.

Thanks, Harold
