# @test
# @bug 4731671
# @build libraryCaller
# @run shell SolarisRunpath.sh
# @summary Verify that Solaris LD_LIBRARY_PATH rules are followed
# @author Joseph D. Darcy

# The launcher has been updated to properly take account of Solaris
# LD_LIBRARY_PATH rules when constructing the runpath for the Java
# executable.  That is, data model dependent LD_LIBRARY_PATH variables
# are tested for and override LD_LIBRARY_PATH if present.  The current
# launcher design relies on LD_LIBRARY_PATH settings to ensure the
# proper jre/jdk libraries are opening during program execution.  In
# the future, this dependence might be removed by having the vm
# explicitly dlopen the needed files.  If that change occurs, this
# test will be harmless but no long relevant.

# A more robust test for Solaris SPARC would set the different
# LD_LIBRARY_PATH variables while also varying the -d[32|64] options
# to make sure the LD_LIBRARY_PATH of the *target* data model were
# being respected.  That is "java -d64" should use the 64-bit
# LD_LIBRARY_PATH while "java -d32" should use the 32-bit
# LD_LIBRARY_PATH regardless of the data model of the "java" binary.
# However, by default builds do not contain both 32 and 64 bit
# components so such a test would often not be applicable.


# If the test is not being run on a Solaris box, SPARC or x86, the
# test succeeds immediately.
