I'm getting empty reports when run with Java8. Specifically, Oracle jdk1.8.0_65 on OSX and OpenJDk 1.8.0_45-internal-b14 on ubuntu. I'm afraid it's not much to do on, but I did file HBASE-14933 for tracking any necessary changes on our end.

This is as of commit 2ac917f.

Hello,

Thank you for reporting the issue.

What is your Ubuntu version? I'll try to debug the tool on it.

Hello,

I've just tried the tool on the clear Ubuntu 15.04 Live x86_64 with OpenJDK-8 and all internal tests were passed:

]$ sudo apt-get install openjdk-8-jdk
]$ perl japi-compliance-checker.pl --test   

verifying detectable Java library changes
using Java 1.8.0_45-internal
reading classes 1.0 ...
reading classes 2.0 ...
comparing classes ...
creating compatibility report ...
result: INCOMPATIBLE (Binary: 35.7%, Source: 42.9%)
total "Binary" compatibility problems: 55, warnings: 20
total "Source" compatibility problems: 60, warnings: 3

Could you please run

japi-compliance-checker --test

And compare the output?

Also please check if you are using the latest version of the tool:

japi-compliance-checker --version

If all is OK please give me the sample JARs where the tool returned empty report and I will debug the tool on them.

Meanwhile I'll try to run the tool with the Oracle's JDK.

Thank you.

This can be closed, @aponomarenko; we've solved the underlying issue in our HBase script and I can confirm that the tool works on JDK8.
