Memory leak in dsimport branch

[dzwicker]

I have tried the new version of cdi-query (eta-module for deltaspike???) in the disport branch. After this we run very quick in some OutOfMemoryExceptions. After some visualVM sessions i figured out that seems to be a leak in the DelegateQueryBuilder. The instances are not released and every run of our integration tests the instance count was doubled... I attache some visualVM screenshots showing the heap/sampler state after boot, the first run of the integration tests, after GC call and after second round of ITs. I attached screenshots of the app running with cdi-query-1.0.0-ALPHA5 after boot, first run of IT and 5 runs of IT (with the dsimport branch only 2 runs are possible because of OutOfMemories), too.

After boot:

1. run:
   
   

GC called:

1. run:
   
   

GC called:

Using cdi-query-1.0.0.ALPHA
Boot:

1. run:
   

after running the integration tests 5 times:

Let me know if there something i can do to help with this issue.

Great stuff - thnx a lot for the analysis! Will have a look what's going on.

From a quick look at the code - I guess that's a consequence of moving the QueryHandler to application scope. Will think about how to properly clean this stuff up....
