[bug] Import of measure "NumberOfComponentItems" crashes the platform.

[NG-GOM]

Summary

Import of the "NumberOfComponentItems" crashes the platform and leaves it in an unusable state.

Details

I successfully deployed and tested several metrics on a freshly installed MEASURE platform.

Then I tried to import the "NumberOfComponentItems" measure. It hasn't appeard on the Measures catalog and the following error appeard on the console :

Resolved exception caused by Handler execution: java.lang.NullPointerException

I then tried to upload some other measures to the catalog ("NumberOfTransactionalComponents"), but they didn't appear and I haven't seen any error on the console.
I restarted the platform, but it still didn't work.
@aabherve advised me to manually remove the metric from the platform's storage directory, but it still was impossible to import new measures to the catalog.

After re-installing the platform and all of its dependencies, import of the "NumberOfTransactionalComponents" measure worked successfully.

Unfortunately, I haven't been able to get the original platform back to a nominal state.
