Here is the suggested trivial fix:
Since the changes for JDK-8005942/JDK-8009463 that commands
containing spaces cannot be used with Runtime.exec(String). Applications
should really specify the command and its arguments using the
Runtime.exec methods that take an array, or alternatively use
ProcessBuilder as recommended since jdk1.5.
Nevertheless we would like to minimize the impact for legacy Windows OS
Java application. For application that works without the Security
Manager, the "jdk.lang.Process.allowAmbigousCommands" Java property
could be defined programmatically or by program switch
[-Djdk.lang.Process.allowAmbigousCommands]. Definition of the property
returns old verification procedure for program name and program
arguments with full risk of security vulnerabilities.
For compatibility reason the case of quoted executable name in the
Runtime.exec(String </j2se7/api/java/lang/String.html>) was supported.
If the Security Manager is installed, it is called twice for this case:
for space-based paring result and result of extended parsing procedure
that takes quotation into account. We do not guaranty the backward
compatibility for any call with quoted executable name, but in general
