I have error under java 8:

My java version:
java version "1.8.0_45"
Java(TM) SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.45-b02, mixed mode)

This error appear recently (earlier everything worked ok).

Can you check your classpath and see what version of ASM you have? Is it v4 or v5? If it's v4, maybe you could try the version mentioned in #3?

Changing verifier version to 0.4.2-asm4-SNAPSHOT didn't help:

I think that problem is caused by Opcodes.ASM4 in https://github.com/adamw/veripacks/blob/release-0.4.2/verifier/src/main/scala/org/veripacks/reader/dependencies/DependencyVisitor.scala#L163 and other occurence.

[adamw]

I just published 0.4.2-SNAPSHOT which uses Opcodes.ASM5 - could you check?

[kkarwows]

Can't find 0.4.2-SNAPSHOT in maven repos (https://oss.sonatype.org/content/repositories/snapshots/org/veripacks/veripacks-verifier_2.11/).

[adamw]

It's there now, I published yesterday but no idea why it didn't come up - sorry

[kkarwows]

With version 0.4.2-SNAPSHOT everythink works fine on java 8!

[adamw]

Great, I just released 0.4.3, should be in central in an hour or so

[kkarwows]

Thanks!
