Compiler fails to parse Java class files with missing annotations #7751

scabug · 2013-08-14T14:04:13Z

Attempting to use the Guava cache package without the JSR-305 and JSR-330 annotations in the classpath results in some rather strange error messages:

warning: Class javax.annotation.Nullable not found - continuing with a stub.

At a minimum, the compiler should explain that compilation against Java class files with missing annotations is not allowed, and not emit all of those other strange messages.

It would be preferable, however, for the compiler to proceed without the missing annotations, like the Java compiler does.

It seems that others have run into this problem as well, but I couldn't find any mention of it in the issue tracker.

The text was updated successfully, but these errors were encountered:

Kris Nuttycombe (nuttycom) said (edited on Nov 13, 2013 8:53:41 PM UTC):
A possible workaround: I ran into this issue when pruning dependencies from a project. Interestingly, the pruning step that first revealed the error was removing this dependency:

"com.google.code.findbugs" % "jsr305" % "2.0.0",

And reintroducing the dependency fixed the error, though I've not done any detailed experimentation to determine why.

And, now actually reading to the top of the ticket, I realize that this was already know. Sorry for the noise.

I've just encountered same issue with Spring 4.0.1.RELEASE, Spring-Scala 1.0.0.RC1, Scala 2.10.3, sbt 0.13.1 and JDK 1.7 update 45. Spring 4.0.x is using a JDK 8 annotation java.lang.annotation.Repetable (see here). Compilation with Scala, of class which makes use of Spring annotation annotated with @Repeatable, fails:

Sean Owen (srowen) said:
FWIW I am also seeing apparently the same problem in the following situation, and I have a work-around for the situation, which might help others or highlight a possible improvement to the scala compiler:

Project depends on hadoop-client
hadoop-common depends on commons-logging
We exclude commons-logging dependency from hadoop-client and instead replace it with SLF4J's shim jcl-over-slf4j, a drop-in API replacement

We get:

[WARNING] Class org.apache.commons.logging.Log not found - continuing with a stub.
[ERROR] error while loading FileInputFormat, class file '/Users/srowen/.m2/repository/org/apache/hadoop/hadoop-core/1.0.4/hadoop-core-1.0.4.jar(org/apache/hadoop/mapred/FileInputFormat.class)' is broken

The class is available in jcl-over-slf4j, but is marked as "runtime" dependency since it is not used directly, and not needed -- by the likes of javac at least -- at compile time.

Changing the scope to "compile" makes it work, presumably because then scalac sees it, and it seems that without seeing it, this error occurs. I don't know if it's realistic, but ideally the behavior would match that of javac, which does not need knowledge of a dependency like this.

@retronym said:
We've improved this a bit in Scala 2.10.4 (or was it 2.10.3?) What version are you testing with?

You can use scope = provided to keep it on the compile time classpath but exclude as a runtime/transitive dependency of your project.

scabug · 2014-02-08T16:45:04Z

Sean Owen (srowen) said:
I'm using 2.10.3. The thing is we want it available exactly at runtime, and not compile time -- the opposite. It's not a big deal to use compile scope and then simply not actually use it directly.

scabug · 2014-02-08T17:28:34Z

@retronym said:
I found the change I was thinking of. It is #7439, which is fixed in 2.10.4.

Our "stub symbol" handling regressed badly before that fix. We still run into problems with it, but I would be interested to hear how your scenario is handled in 2.10.4-RC2.

Sunghyouk Bae (debop) said (edited on May 10, 2014 10:01:25 AM UTC):
It has occur in 2.10.3, 2.10.4, 2.11.0 in compile time.

I use spring 4 @scheduled that use @repeatable in JDK 8

I also fixed #8442 in the upcoming 2.11.1 / 2,10.5 which manifests in the same way.

~~Ran into this with Scala 2.11.8. Regression?~~ [-A workaround- Compiler warnings are solved by including Google's JSR-305 library (as described in #8978) ~~fixes this~~ which may be helpful to projects with "-Xfatal-warnings".

@retronym, I looked before I leapt. It's while I was making a sample project I noticed my error came from "-Xfatal-warnings". So… non-issue. Sorry for the noise!

SethTisue · 2023-08-13T22:40:52Z

It's a bit hard to be fully certain, reading through the above history, but it appears this was probably fixed years ago.

We can reopen if someone steps forward with a reproduction on current Scala 2.
