      Description

      Hi,
      We are periodically getting issues with the hudson.util.jna.Kernel32 class not being found when plugins are calling the isSymlink method.

      [xUnit] [INFO] - [UnitTest-1.4 (default)] - 1 test report file(s) were found with the pattern 'tests.xml' relative to 'C:\Jenkins\jobs\NetworkTeam Test\workspace' for the testing framework 'UnitTest-1.4 (default)'.
FATAL: Could not initialize class hudson.util.jna.Kernel32
java.lang.NoClassDefFoundError: Could not initialize class hudson.util.jna.Kernel32

	at hudson.model.ResourceController.execute(ResourceController.java:88)
	at hudson.model.Executor.run(Executor.java:236)

      The class file seems to be present and correct compared with the github versions and we are running with Admin access to the filesystem.

      Any help would be appreciated.

            Since this is fixed on the trunk, will/can this be marked as resolved soon so that it can be released into 1.504?

            And what is also very important when it could be released in LTS?

            [FIXED JENKINS-15466] More robust handling of Windows JNA errors.
            b5ed319 already caught linkage errors but then unconditionally returned false from Util.isSymlink, which is wrong;
            we want to fall back to the generic File.canonicalPath comparisons in this case.
