+    <td><p>
+    		Previously, when debugging an OT/J or OT/Equinox application,
+    		changes made to the source code of the running application could not be applied on the fly,
+    		because the JVM would detect signature mismatches.
+    		This was caused by the fact that during hot code replacement the Object Teams bytecode transformer was not used. 
+    	</p>
+    	<p>
+    		This has been fixed by enabling the Object Teams transformer to re-weave already loaded classes.
+    		Additionally, for OT/Equinox debug launches a new Java agent has been developed
+    		to trigger weaving also for hot code replacement (which is not supported by the underlying adaptor hooks in Equinox).
+    		This agent is automatically added to the Java command line for all OT/Equinox debug launches. 
+    	</p>
+    	<p>
+    		As the result it is no possible to directly see the effect of source code changes even in woven
+    		classes without restarting the application. Note, that hot code replacement is limited by the JVM
+    		to changes that do not affect any signatures.
