Assigning to Jason for initial investigation. I put a breakpoint in ElementChangedEvent to see what events are being generated. Two events are created when I drop the jar; here are the deltas:
Java Model[*]: {CHILDREN}
W[*]: {CONTENT}
ResourceDelta(/W/WebContent)[*]
Java Model[*]: {CHILDREN}
W[*]: {CHILDREN | RESOLVED CLASSPATH CHANGED}
C:\dev\runtimeWorkspaces\WTP_32\W\WebContent\WEB-INF\lib\EJBSingleton.jar[*]: {CONTENT | ADDED TO CLASSPATH | ARCHIVE CONTENT CHANGED}
Then, when I delete the jar the following two event deltas are created:
Java Model[*]: {CHILDREN}
W[*]: {CONTENT}
ResourceDelta(/W/WebContent)[*]
Java Model[*]: {CHILDREN}
W[*]: {RESOLVED CLASSPATH CHANGED}
I've also confirmed that the classpaths are being properly updated. These classpath containers are set via JDT API, and any events that are fired are based on these classpath containers being set. From the standpoint of the Web App Libraries classpath containre, this is all working as designed. If the JDT events I'm seeing are not correct, please follow up directly with the JDT team. There have been cases in the past where the Web App Libraries classpath container has exposed bugs in JDT, and this may be another one of those cases.
It appears that this is the one:
Java Model[*]: {CHILDREN}
W[*]: {CONTENT}
ResourceDelta(/W/WebContent)[*]
The resource delta contains the removal of the library file so I key of that. This appears to be the expected behavior, although it seems inconsistent to me.

If I copy a jar file into the WEB-INF/lib of a dynamic web project, I get the following IJavaElementDelta in the corresponding ElementChangedEvent: org.eclipse.jdt.core.ElementChangedEvent[source=Java Model[*]: {CHILDREN} ContextParamTests[*]: {CHILDREN | RESOLVED CLASSPATH CHANGED} C:\dev\workspaces\runtime-New_configuration\ContextParamTests\WebContent\WEB-INF\lib\metainf-taglib.jar[*]: {ADDED TO CLASSPATH}] When I then delete it, I would expect to get a similar event but with the "REMOVE FROM CLASSPATH" flag set. This is what happens if I manually create a library on the project class path and then remove it.
