We are launching slaves on unix machines via SSH (using the Jenkins SSH Slaves plugin). The Jenkins master is running on Windows and we have a mix of unix and Windows slaves. For the unix slaves, LD_LIBRARY_PATH and DYLD_LIBRARY_PATH are not set up properly. Looking at the source, the problem is in STAFInstallation.java. The method getLibraryDir() calls Hudson.isWindows() which runs on the master, not on the slave. This is also a problem for getJStafJarFile().

Error info on Linux (also fails against Mac slave):
