I made it so that we no longer ever use JarURLConnection to read the resources (template files) that AutoValue needs. Instead, we always open the jar where the AutoValue code lives explicitly, and read the resources out of it. That's probably a bit more expensive, but only happens once per template and per compilation.

@eamonnmcmanus

I dug around in the code for a bit to see what might have changed between 1.8.2 and 1.10.2 that could be a cause for this, and what looked most likely to me is the change to parse files for #parse nodes at template evaluation time rather than template parse time.

It seems like that could be a problem here because AutoValueTemplateVars holds a pre-parsed static final Template for autovalue.vm, which will then need to try to open and parse (and cache) equalshashcode.vm (always) and builder.vm (if there's a builder -- this seems to be where the exception is occurring in this case). The issue then could have to do with how TemplateVars.class.getResourceAsStream is used to to open the streams to read those from.

All that said, I'm not sure why opening that stream seemingly must be succeeding in this stack trace and the exception is then occurring while reading from from it. Maybe something is closing the original jar stream that the static reference to TemplateVars.class was loaded from, making the streams opened from it with getResourceAsStream also closed?

Thanks @cgdecker, I think your theory is correct.

From the stack traces, it looks like this is happening on Java 8. I think the issue is JDK-6947916, which was fixed in Java 9. We already have a workaround but as Colin notes that only applies when the original autovalue.vm is read. The #parse happens later, outside the try/catch where the workaround is active.

I put a lot of effort into making this workaround, including a ridiculously complicated regression test, then unknowingly undid it all with the change Colin mentions.

While it's probably possible to come up with a new workaround, I think it would be a lot easier just to build with a more recent JDK. JDK 8 was released in 2014 and is more or less EOL now. Unless you can confirm that it is in fact a more recent JDK? (I'm assuming it's 8 because there are no module names in the stack traces.)

(You can still build with --target 8 to produce Java-8-compatible .class files.)

Looking at the failed build link, it looks like Maven should be compiling with JDK 11 in this case:

I wonder if changing the distribution to something else (oracle or adopt maybe?) would change anything.

Thanks for looking into this!

Right, it should be Java 11.

I got locally too with

openjdk version "11.0.17" 2022-10-18
OpenJDK Runtime Environment Temurin-11.0.17+8 (build 11.0.17+8)
OpenJDK 64-Bit Server VM Temurin-11.0.17+8 (build 11.0.17+8, mixed mode)

After running while mvn -T32 clean compile -DskipTests -e; do done at DataflowTemplates for a couple of minutes.

It's hard to bisect because it takes a bit to run, but I am pretty confident it is not happening with a single thread (or the probability is minimal), as the loop ran for hours with -T1.

Appreciate you guys looking -- but note that I understand this is a very specific use-case and this is not urgent. We reverted to 1.8.2 for the time being.

eamonnmcmanus avatar eamonnmcmanus commented on September 28, 2024

I'm still puzzled at the absence of module names in those stack traces. Could you do this experiment in your environment?

$ jshell
|  Welcome to JShell -- Version 11.0.17
|  For an introduction type: /help intro

jshell> new Throwable().printStackTrace()

        ...

It's those java.base/ that I would expect to see in a stack trace from the JDK 11 compiler. Unless the Zulu JDK doesn't do that?

I'm persisting here just because it still seems like a big coincidence that (1) the stack traces look like Java 8 and (2) the symptoms correspond exactly to a bug that was fixed in Java 9.

cgdecker avatar cgdecker commented on September 28, 2024

Curiously, I just ran the jshell binary from zulu11.66.15-ca-jdk11.0.20-linux_x64 and saw module names as expected, so I do wonder if something weird is going on.

eamonnmcmanus avatar eamonnmcmanus commented on September 28, 2024

For example, if the pom.xml were doing something like this then the compilation could end up using JDK 8 even though Maven itself is running with JDK 11.

honnix avatar honnix commented on September 28, 2024

We also hit this problem quite often these day. Is there a plan to get this prioritized a bit? Thank you.

Can you confirm whether you are using JDK 8 or a later JDK version?

from auto.

honnix avatar honnix commented on September 28, 2024

I can confirm we use Java 11 and compile with 11 as release target as well. We have Maven parallell build enabled.

from auto.

eamonnmcmanus avatar eamonnmcmanus commented on September 28, 2024

OK. If you have an exception stack-trace, can you show it? I'm curious if it contains module names, as I mentioned in an earlier comment. But I think it is probably possible to rework the code so that the existing workaround is applied more generally.

Sure. There it is:
