Currently, jtreg incorrectly confuses the concept of the /directory/ in which the test's class will be written with the /classpath/ used to locate all of the test's classes, including any library classes.  It provides env variable TESTCLASSES and system property test.classes, and tests use these to mean both a directory and a classpath.

jtreg will be fixed to separate the two concepts, such that TESTCLASSES/test.classes will continue to mean the /directory/ in which the test's class will the written, and will introduce TESTCLASSPATH/test.class.path for the classpath used to locate all the test's classes.

This change only affects a small number of tests, which use both @library and TESTCLASSES. A number of serviceability tests are affected, 
FAILED: sun/tools/jcmd/jcmd-big-script.sh
FAILED: sun/tools/jcmd/jcmd-f.sh
FAILED: sun/tools/jcmd/jcmd-help-help.sh
FAILED: sun/tools/jcmd/jcmd-pid.sh
FAILED: sun/tools/jinfo/Basic.sh
FAILED: sun/tools/jmap/Basic.sh
FAILED: sun/tools/jps/jps-m_2.sh
FAILED: sun/tools/jps/jps-Vvml_2.sh
FAILED: sun/tools/jstack/Basic.sh
However, all the failures are caused by issues in shared library code, meaning that only that code needs to be updated.


SUGGESTED FIX The fix is to update the tests where they are using TESTCLASSES/test.classes as a classpath. To ease migration onto the new jtreg, it is suggested that the tests check to see if the new variables are defined (i.e. new jtreg) and to fall back on the old variables if they are not defined (i.e. old jtreg). In shell terms, this can be written ${TESTCLASSPATH:-${TESTCLASSES}}
