smartsvn 8.6 on Solaris 10 (x86) JavaHL-Version Error

Hi,
starting smartsvn 8.6 on solaris 10 causes
java.lang.reflect.InvocationTargetException
at sun.reflect.NativeMethodAccessorImpl.invoke0(Nativ e Method)
[...]
at QBootLoader.main(SourceFile:114)
Caused by: java.lang.NoClassDefFoundError: org/apache/subversion/javahl/SubversionException

Installed Coponnts:
SVN-Client http://www.wandisco.com/system/files...svar=solaris10
Java(TM) SE Runtime Environment (build 1.7.0_67-b01) Java HotSpot(TM) Client VM (build 24.65-b04, mixed mode)
GTK-2.1/2.10.0 (from OpenCSW)

After creation of a symlink in smartsvn8.6's lib-Directory (subversion-1.8-javahlext.solaris.x86.jar -> /opt/WANdisco/lib/svn-javahl/svn-javahl.jar) a Messagebox appears:
Title:"Invalid JavaHL"
Text:"Invalid JavaHL and or Runtime version. Alt least JavaHL 1.8.5 and subversion runtime 1.8.5 versions are requirerd. Please verify that you have installed [...]"

And so I did:
Integration of /opt/WANdisco/lib/svn-javahl/svn-javahl.jar in a basic java App and running org.apache.subversion.javahl.SVNClient.Version() returnes: "svn: 1.8.10 (r1615264), jni:0.9.0".
Also, the integration of the WANdisco javahl-Adapter in Eclipse-Subversive-SVN-Connector succeeded.

What did I miss ?

Thanks and bst regards,

Hanno
