Description Stephan Herrmann CLA 2011-04-11 18:12:47 EDT 
The aspect plugin org.eclipse.objectteams.otdt.apt requires the
fragment org.eclipse.jdt.compiler.apt to be resolved.
However, on JVM 1.5 the latter is not loaded due to 
Bundle-RequiredExecutionEnvironment: JavaSE-1.6

This causes havoc during loading of aspectBindings and teams:
An error logged from the TransformerPlugin:
Required fragment org.eclipse.jdt.compiler.apt is not resolved (aspect binding of org.eclipse.objectteams.otdt.apt)

Plus an exception logged to the console:
java.lang.ClassNotFoundException: org.eclipse.jdt.internal.compiler.apt.dispatch.AnnotationDiscoveryVisitor not found.

Comment 1 Stephan Herrmann CLA 2011-04-14 05:34:57 EDT 
Fixed in r1424 by adding Bundle-RequiredExecutionEnvironment: JavaSE-1.6
also to org.eclipse.objectteams.otdt.apt.

Additionally, r1422,25  safe guard against loading teams from an
unresolved bundle (shouldn't happen).
