Invalid layout of java.lang.StackFrameInfo field

[ebourg]

I've built DCEVM 11.0.5+5 in Debian, but it fails to start with the following error (using OpenJDK 11.0.6+10):

$ java -dcevm -version
[0.009s][error][class] Invalid layout of java.lang.StackFrameInfo field: bci type: S
Error occurred during initialization of VM
Invalid layout of preloaded class: use -Xlog:class+load=info to see the origin of the problem class

What version do you need for Ubuntu? Last tag on adopt branch is 11.0.7+6 :

Debian and Ubuntu follow the GA releases:

https://wiki.openjdk.java.net/display/JDKUpdates/JDK11u

Currently it's 11.0.6+10. OpenJDK 11.0.7 will be released next month.

[skybber]

There is new a branch dcevm11-jdk-11.0.6. It should be checked if it is stable enough.

[ebourg]

Thank you, I'll give it a try.

It doesn't compile unfortunately (using GCC 9):

I've checked the problem, the offset method is inline and did not change for more then 1 year:

1232: int alignment = fd->offset() - _position;

[skybber]

Looks fixed now, there was some change in include hiearchy: https://travis-ci.org/TravaOpenJDK/trava-jdk-11-dcevm

[skybber]

Look there is another bug. Please don't release it .

[skybber]

It can be released. I have problem with non static inner classes, but it has been in the DCEVM for years. Looks that bytecode verifier could be turned off on redefinition to not have this problems.

[ruediste]

@skybber: any news on this latest problem?

[skybber]

Bytecode verifier is turned off now in redefinition no, to not have problems with inner classes. So it is fixed.

[ebourg]

I confirm it's ok now, thank you.

We got similar issue and below are the details.

Error Message :

JDK Version: 11.0.13+8 (build 11.0.13+8)

Windows OS : 10.

Type of Machine : VM

Observations: Issue is very sporadic .

What could be the root cause for this and can anyone help me on this?
