Description

Sometimes Groovy module's extension methods don't inject to target Class when get the module by Grab annotation.
I attached test code but easy way to regenerate this issue is, use tim yates's groovy-stream:

@Grab( 'com.bloidonia:groovy-stream:0.6.2' )
import groovy.stream.Stream


println([1,2,3].iterator().toStream())

fails indeterminately in my environment(1 time per 3 .. 10 trial, or serial)

Caught: groovy.lang.MissingMethodException: No signature of method: java.util.ArrayList$Itr.toStream() is applicable for argument types: () values: []
Possible solutions: toString(), toString(), toSet()
groovy.lang.MissingMethodException: No signature of method: java.util.ArrayList$Itr.toStream() is applicable for argument types: () values: []
Possible solutions: toString(), toString(), toSet()
at s.run(s.groovy:5)

Following code seems to success.

groovy.grape.Grape.grab(['group': 'com.bloidonia', 'module': 'groovy-stream', 'version': '0.6.2'])
println([1,2,3].iterator().toStream())

Is it related to static class initializer invocation timing? I don't sure.

Attached code trying to generate this problem in test case, but it don't work
under testing framework by some reason I can't tell.
So to regenerate it you have to use groovy command from shell:

% unzip test.zip
% cd test
% ./gradlew uploadArchives # put module into /tmp/myRepo
% groovy src/test/resouces/GrabTest.groovy
Caught: groovy.lang.MissingMethodException: No signature of method: java.lang.String.hello() is applicable for argument types: () values: []
Possible solutions: sleep(long), sleep(long, groovy.lang.Closure), split(), next(), split(), next()
groovy.lang.MissingMethodException: No signature of method: java.lang.String.hello() is applicable for argument types: () values: []
Possible solutions: sleep(long), sleep(long, groovy.lang.Closure), split(), next(), split(), next()
at sample.GrabTest.main(GrabTest.groovy:10)

P.S. If you put the groovy-module jar in your class path, it succeed.
