For langtools, the minimal usual parameters are

     -s -ignore:quiet -v:summary test/

-s
     use samevm mode (runs most tests in the same JVM, instead of each 
test in its own JVM)

-ignore:quiet
     a few remaining tests use @ignore;  this option tells jtreg to 
ignore these tests

-v:summary
     generate one line of output per test run;
     this is good when running the tests from the command line
     use -v:summary,nopass if you just want to know about failed/error 
results

test/
     Run all the tests (this is a path to a folder, so may be 
langtools/test depending on your current directory)

Personally, I always use -w and -r to override the default locations of 
the work and report directory, using something like
     -w build/jtreg/work  -r build/jtreg/report

Also, for langtools, set assertion options:
     -ea:com.sun.tools... -esa


New:

With jtreg 4.1 b03, you can replace "-s" (samevm mode) with "-agentvm" 
(agentvm mode). AgentVM mode is "like samevm mode, but better". This 
allows you to run tests concurrently, in separate JVMs.  Specify the 
number with -concurrency:N.   Last time I tried this on my relatively 
new MacBook Pro, I could run all the langtools tests in 2-3 minutes. 
:-)  See http://blogs.oracle.com/jjg/entry/jtreg_update1 for more details.


----

Separately, if anyone is building/debugging *just* langtools, you can 
build just the langtools repository, and then use something like
     -jdk:RECENT-JDK   -Xbootclasspath/p:LANGTOOLS/build/classes.jar

This saves having to build the entire JDK every time you edit langtools.
