with grails 2.0.0

All the test cases pass using grails 2.0.0

+ git checkout grails-2.0.0;
+ export GRAILS_HOME=...;
+ export PATH=$GRAILS_HOME/bin:$PATH
+ grails clean;
// all pass
+ grails test-app --echoOut UserControllerSpec UserControllerSpockMockSpec UserServiceIntegrationSpec UserServiceIntegrationSpockMockSpec; 
 

with grails 2.2.3

The spock unit mock tests seem to work in isolation, but if combined with any other test cases that use Grails Mock they seem to fail. i.e if I run UserControllerSpockMockSpec in isolation it works but if run together with "UserControllerSpec UserControllerSpockMockSpec" it will cause failure..

+ git checkout master;
+ export GRAILS_HOME=...
+ export PATH=$GRAILS_HOME/bin:$PATH
+ grails clean;
 

// works in isolation
+ grails test-app --echoOut UserControllerSpockMockSpec; 
// one test case fails 
+ grails test-app --echoOut UserControllerSpec;  
// failures in both specs, but UserControllerSpockMockSpec worked in isolation
+ grails test-app --echoOut UserControllerSpec UserControllerSpockMockSpec;  

for integration specs the spock Mock tests seem to fail in isolation also..

// fails
+ grails test-app --echoOut UserServiceIntegrationSpec;  
// fails
+ grails test-app --echoOut UserServiceIntegrationSpockMockSpec
