Jex Jexler created GROOVY-8108:
----------------------------------
Summary: Groovy sources with Grape grabs fail to load from
bytecode (race condition)
Key: GROOVY-8108
URL: https://issues.apache.org/jira/browse/GROOVY-8108
Project: Groovy
Issue Type: Bug
Components: Compiler
Reporter: Jex Jexler
The bytecode of Groovy sources with Grape grabs contains a static initializer
that calls Grape#grab(...). But since the bytecode also references classes that
can only be loaded after grabbing the dependencies and adding them to a parent
class loader, loading such referenced classes may fail due to a race condition
with a NoClassDefFoundError.
See the thread titled "Grape and loading classes that extend
java.lang.Exception from compiled Groovy bytecode" in the Groovy Dev Mailing
List of Feb/Mar 2017 for sample sources and discussion:
http://groovy.329449.n5.nabble.com/Grape-and-loading-classes-that-extend-java-lang-Exception-from-compiled-Groovy-bytecode-tp5738786.html
Although it appears almost certain that no fix will be possible, except maybe
as part of a redesign for major release, I am reporting this so that it is
documented.
