RFR: JDK-8242282: Test sun/tools/jps/TestJps.java fails after JDK-8237572

[Alex Menkov]

Hi all,

Please review the fix for
https://bugs.openjdk.java.net/browse/JDK-8242282
webrev:
http://cr.openjdk.java.net/~amenkov/jdk15/jpsTest_ClsNotFound/webrev/

The test creates jar with test classes and run it with "java -jar 
<jar_file>".
The problem is single "@run Test" tag is executed by JTreg 
inconsistently - sometimes library classes are compiled to test 
directory, sometimes - to library directory.
The fix explicitly forces required library classes compilation (so 
library files are compiled to library dir) and add classpath directories 
to jar manifest.
