-------------------------------------
Summary: Binary incompatibility problems between compiled code in
Groovy 2.4.7 vs 2.4.9
Key: GROOVY-8107
URL: https://issues.apache.org/jira/browse/GROOVY-8107
Project: Groovy
Issue Type: Bug
Reporter: Graeme Rocher
There are currently various binary incompatibility problems that are presenting
a challenge for us moving forward with upgrading to Groovy 2.4.9 in Grails.
One of them is Groovy traits compiled with Groovy 2.4.9 are not usable in
Groovy 2.4.7 due to the following exception:
{code}
Error:Groovyc: While compiling tests of grails-datastore-gorm-hibernate5_test:
BUG! exception in phase 'semantic analysis' in source unit

This is an issue and IMO there should never be binary incompatible breaking
changes between different path release of Groovy 2.4.x.
The other issue is https://issues.apache.org/jira/browse/GROOVY-8048
Which is marked as fixed, but currently code already compiled in Groovy 2.4.7
is throwing a NPE such as:
{code}
Caused by: java.lang.NullPointerException: null

{code}
We can't really ask people to start recompiling existing published libraries
for a patch release of Groovy so are looking for a path forward with these
problems.
It is my opinion that we should be aim to never break binary compatibility in a
major release let alone in a patch release.
