# @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.
