    [ https://issues.jboss.org/browse/JBIDE-9140?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12619812#comment-12619812 ] 

Denis Golovin commented on JBIDE-9140:
--------------------------------------

"it indicates to the runtime that your plug-in should run even if an optional plug-in dependency is missing or not resolved" (c). It works only if there is no direct references to classes from optional bundle (i.e Java Reflection is used), thus it is not required for compilation.

That is how PDA build used to work (i'm not sure it is work the same way in 3.7). It just didn't include optional dependency in build classpath in generated ant build. 

This behavior also lets avoid Class Definition Not found exceptions.

For example, if you have orq.bundle2.Class1 imported in class1 that belongs to org.bindle1 and org.bundle1 is marked as optional dependency, compilation now passes without errors, but what is going to happen after orq.bundle2 is installed without accessible org.bundle1? P2 lets org.bundle2 to be installed and class not found exception is thrown on attempt to load org.bundle2.Class1.
