Technical discussion about usage of the jtreg test harness

Setting PATH for jtreg

Hi,

the jtreg FAQ states in point 4.1:

As per spec, the only shell environment variables that are propagated
into the test's JVM are:

    * Linux and Solaris:
          o PATH is set to /bin:/usr/bin

However in our environment, the compilers are installed on a global
NFS-share. I have the problem that all the tests which use gcc to
compile native JNI files fail because they get a wrong version of gcc
from /usr/bin.

Is there any possibility how I can override the PATH variable for jtreg?

Regards,
Volker

Re: Setting PATH for jtreg

Volker,

jtreg has a -e option for tunnelling env variables into scripts.
Use "jtreg -help -e" for info.   Any values specified with -e
override any defaults set up for the test. So, it should work
to use -e:PATH to override the system default value of PATH
with the value from your current environment.

Re: Setting PATH for jtreg

Hi John,

thank you for the fast help. "-e:PATH" indeed solved the problem.

Now that you pointed me to the option I must admit that it is really
there. Unfortunately, I didn't found it before, although I did "jtreg
-help" several times. This may be perhaps because it is in the
"JDK-related Options". For me, this is not strictly a JDK-related
option and would better fit into the "General Options". But this is of
course purely a matter of taste:)

However I think a small advice in the FAQ section 4.1 cited below that
PATH can be overriden with the "-e:PATH" option may be helpfull to
others as well.

Once again thank you and best regards,
Volker

Re: Setting PATH for jtreg

Volker,

Thank you for the update and suggestions.

Your comment about it being more of a general option
and not a JDK option and your suggestion about
the FAQ are noted.
