+JDK-8290832: It is no longer possible to change "user.dir" in the JDK8
+======================================================================
+A change, JDK-8194154, was introduced in the 8u342 release of OpenJDK
+causing the JDK to ignore attempts to set the `user.dir` property.
+While this change is suitable for a major release (it was originally
+introduced in the initial release of OpenJDK 11), changing the
+behaviour of such a property in an update release creates
+compatibility issues in software that relies on the behaviour in prior
+versions of OpenJDK 8.  As a result, we have reverted this change in
+8u345.
