Hi Dalibor,

It took me a while to get back to this, but I just gave this a try.
Jacoco has released 0.8.3 version with this fix to support Java 13 and I
gave it a try against the original project which was running into this
issue. I can now confirm that this now works fine with Jacoco 0.8.3 and
Java 13 (even the latest EA 8 build).

Our Ant testsuite against this EA version of JDK 13 has passed fine on
Linux. However, one of our other projects within the Ant umbrella has
shown an issue with the Jacoco library usage (which internally uses ASM
library). Narrowing this down to a simple standalone Java program has
shown that this version of Java isn't compatible with ASM 7.0. It runs
into:


java.lang.IllegalArgumentException: Unsupported class file major
version 57
  at org.objectweb.asm.ClassReader.(ClassReader.java:184)
  at org.objectweb.asm.ClassReader.(ClassReader.java:166)
  at org.objectweb.asm.ClassReader.(ClassReader.java:152)


while trying to instrument a class compiled with that JDK 13 EA build. I
haven't yet had a chance to see if there's a newer version of ASM which
works against this version, but my quick checks haven't shown any newer
versions.

Hi Jaikiran,

the changes for experimental support of JDK 13 bytecode have just gone
into jacoco, per https://github.com/jacoco/jacoco/pull/835 .


Thank you for pointing me to that commit, I'll give that snapshot
version a try against our project and see how it goes, over the next few
days.

Hello Rory,

Our testsuite, of the master branch of Ant, has come up clean for both
the JDK 12 build 32[1] and JDK 13 build EA 8[2]. These initial test runs
are only against Linux setup and one of these days I'll run these tests
against Windows as well. In the next few days, I'll run some of our
other Ant projects with these JDK builds (especially JDK 12) to make
sure they are fine too.
