----------------------------------
Summary: Enable GroovyClassLoader to be ParallelCapable
Key: GROOVY-11478
URL: https://issues.apache.org/jira/browse/GROOVY-11478
Project: Groovy
Issue Type: Improvement
Affects Versions: 5.0.0-alpha-10, 4.0.23, 3.0.22
Reporter: Paul King
Assignee: Paul King
GroovyClassLoader is parallel capable but we do not declare it as such by
calling the {{registerAsParallelCapable}} method as per recommended
guidelines[1]. Some frameworks have worked around this using reflection but as
JDK restrictions have tightened in later JDK versions, this has become not
possible. Other workarounds[2] for frameworks to work with non-parallel capable
classloaders have also been deprecated and removed in recent JDK
versions[3][4][5]. See also [6].
