RE: [equinox-dev] Standardize Eclipse Lazy Start

[Thomas Watson <tjwatson@xxxxxxxxxx>]

A lazy activation bundle *will* get
activated before any static initializers are run on class loaded from that
bundle.  This is well before a constructor is allowed to run for a
Class.  The main difference is we activate the bundle after the "trigger"
class has been defined, but before any static initializers are run.  Before
we used to activate the bundle before even searching for the "trigger"
class.  That approach lead to ClassCircularityErrors and possible
deadlock.

Tom, I understand this changes
the relationship between bundle activation and class *loading*.  What's
the relationship between bundle activation and class *construction*?  That
is, suppose code in bundle b calls "new Foo()", where Foo is
a class in bundle a.  Does Foo's constructor run before or after a's
startup method?
 
Thanks,

Hi 

The Equinox team has been working with the OSGi Alliance to standardize
the Eclipse Lazy Start mechanism (i.e. Eclipse-LazyStart).  See the
Equinox WIKI at http://wiki.eclipse.org/index.php/Lazy_Start_Bundles for
details on what is changing in Eclipse 3.3 with respect to Eclipse-LazyStart.

The initial code changes have been released to org.eclipse.osgi and will
be included in tonight's N-Build.  Please let the Equinox team know
if you encounter any unexpected behavior related to lazy bundle activation.

Thanks. 

Tom
