4.1. My test only passes if I don't use jtreg to run it. Why does it fail in jtreg?

By default, tests run using jtreg are each run in a separate JVM. By design, only a limited number of shell environment variables are passed down to the test's JVM. This may affect how a test is run.

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

• Linux and Solaris:
  • PATH is set to /bin:/usr/bin
  • The following are propogated from the user's environment: DISPLAY, HOME LANG, LC_ALL, LC_TYPE, LPDEST, PRINTER, TZ and XMODIFIERS
• Windows:
  • PATH is set to the MKS or Cygwin toolkit binary directory
  • The following are propogated from the user's environment: SystemDrive, SystemRoot windir

A test which relies on any other environment variables will experience difficulties running in jtreg.
