> Various versions of the Sun/Oracle/OpenJDK JVM have issues executing new 
> processes if the default langauge of the JVM is "Turkish".
> The root bug reports of this affecting Runtime.exec() are here...
> * https://bugs.openjdk.java.net/browse/JDK-8047340
> * https://bugs.openjdk.java.net/browse/JDK-8055301
> On systems runining the affected JVMs, with a default langauge of "Turkish", 
> this problem has historically manifested itself in Solr in a few ways:
> * SystemInfoHandler would throw nasty exceptions on these systems due to an 
> attempt at conditionally executing some native process to check system stats
> * RunExecutableListener would fail cryptically
> * some solr tests involving either the SystemInfoHandler or the Hadoop 
> MapReduce code would fail if the test framework randomly selected a turkish 
> language based locale.
> Starting with Solr 4.10, We have worked around this jvm bug in Solr in 3 ways:
> * RunExecutableListener makes it more clear in the logs why it can't be used
> * SystemInfoHandler traps and ignores any Error related to "posix_span" in 
> the same way it traps and ignores other errors related to it's conditional 
> attempts at exec'ing (ie: permission problems, executable not found ,etc...)
> * our map reduce based tests that depend on exec'ing external processes now 
> skip themselves automatically if a turkish local is randomly selected.
> Users affected by this issue who, for whatever reasons, can not upgrade to 
> Solr 4.10, may wish to consider setting the 
> "jdk.lang.Process.launchMechanism" system property explicitly (see below)
> {panel:title=original issue report}
> Jenkin's tests occasionally fail with the following cryptic error...
> {noformat}
> java.lang.Error: posix_spawn is not a supported process launch mechanism on 
> this platform.

> A commonality of most of these failures is that the turkish locale has been
