Using Scala 2.9.1. I have a simple java bean class with an annotation e.g.
@Foopublic class FooBean {
    ...}
I have some scala code that calls a method on FooBean.
The Foo annotation class is in a jar that is not accessible to the scala compiler, but FooBean is available in the compiler's classpath. When the scala compiler tries to compile my scala code, it gives me a "Missing dependency" error:
scala> new FooBeanerror: error while loading FooBean, Missing dependency 'class package.to.Foo', required by /home/raman/test/jars/foobean.jar(FooBean.class)<console>:8: error: FooBean does not have a constructor              new FooBean
This seems very similar to https://issues.scala-lang.org/browse/SI-1135, which is marked as Fixed.
Has SI-1135 been broken in Scala 2.9.1?
Also, on a side note, I noticed that the subsequent times the compilation is executed, the "Missing dependency" error is no longer shown (which can be confusing):
scala> new FooBean<console>:8: error: FooBean does not have a constructor
              new FooBean
Regards,
Raman

I believe this was fixed once and for all as SI-5343 [1] in commit 1684baef [2]. This is not available yet in a released version of Scala, but is available in 2.10.0-M1.

My google-fu failed me this time. Thank you!
