First possible bug in OpenJDK 11 port

Michael Osipov
Folks,

here is a stripped down example from an issue with the new port:

> $ cat ../src/exec/Test.java

>         System.out.println("exit code: " + p.waitFor());
>     }

Fails:

What is causing this issue?

For those who'd like to reproduce the bug: Clone Maven GitHub, try to to
build from master and see the Maven Surefire Plugin failing when it
tried to launch the Surefire Booter.

I can reproduce this with the current port in the FreeBSD ports tree.

It is better behaved with the current code in Github since there has been
some work done on process handling.  With that code the command executes,
but afterwards it throws an exception:

Exception in thread "main" java.lang.RuntimeException: No such process
        at java.base/java.lang.ProcessHandleImpl.isAlive0(Native Method)
        at java.base/java.lang.ProcessHandleImpl.getInternal(ProcessHandleImpl.java:250)
        at java.base/java.lang.ProcessImpl.<init>(ProcessImpl.java:349)
        at java.base/java.lang.ProcessImpl.start(ProcessImpl.java:272)
        at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1107)
        at java.base/java.lang.ProcessBuilder.start(ProcessBuilder.java:1071)
        at TestExec.main(TestExec.java:9)

So there is still some work to do there.  The relevant commit to the github
repo is likely this one:

https://github.com/battleblow/openjdk-jdk11u/commit/4cfeb8650f3f90119aa1e52020ac6ad6620a34ff

This probably means there are still some problems with the
os_getParentPidAndTimings code given that is what isAlive0 is calling
(look at ProcessHandleImpl_unix.c).

Hi Greg,

that for the confirmation. Looks like a showstopper for a developer like
me. Even my webapps won't run because they rely on ProcessBuilder.

Is there anything I can help to get this fixed? That type of C code is,
unfortunately, out of my knowledge.

I want to verify your (and others) great work against all Maven
subprojects as well as CodeHaus to find subtile bugsin the port.

Michael

Hi Greg,

I cloned the repo and have built it. The tests (make test) fail to
compile/run, but the code works flawlessly. I tried maven.git,
maven-intergration-testing.git, maven-scm.git, maven-wagon.git and other
crucial components (from Codehaus Plexus). They all compile and pass
flawlessly. I will additionally try several native ones like Hawt JNI,
Commons Daemon and Tomcat Native.

Thank you very much for the fix!

Michael
