Steps to Reproduce:
Hide

If you test with BRMS 6.4.x on EAP 6, comment out filter-spec as suggested in "Description"

Access to decision-central

Create a project

Upload a Spreadsheet (attached 8000rows-spreadsheet.xls) to make the project heavy. Please ignore Indexing error.

Create a DRL with the below content and save.

rule "hello" when String() then System.out.println("Hello"); end

Click "Validate" for the DRL 5 or 6 times quickly

You will see an empty "Validation errors" popup. If not, try again.

After you see it some times, you can reproduce the issue even with one click.

You may also reproduce the issue by clicking "Validate" for the Spreadsheet. (In this case, you don't need to click very quickly)

Description

When you quickly press "Validate" button multiple times for DRL or Decision table, sometimes an empty "Validation errors" dialog pops up (See attached empty-validation-error.png). After some tries, you will see the empty "Validation errors" more constantly even with one click.

Conditions to reproduce are:

The project (rule assets) is heavy to some extent
The asset where you press "Validate" can be a small DRL. If the asset is large (e.g. spreadsheet), it's easier to reproduce (you don't need to click very quickly).
Reproducible with BRMS 6.4.x and RHDM 7.0.0. But not reproducible with BRMS 6.3.x.

See more details in "Steps to Reproduce"

You will see 3 kinds of errors. Below are errors of BRMS 6.4.8:

After you hit the 3rd error (KieBuilderSetImpl.findResourcesWithErrors()), this issue seems to become constant. (internal KnowledgeBuilderError objects get broken?)

NOTE: If you run BRMS on EAP 6, you have to comment out filter-spec in logger in standalone.xml. If you don't, the error stacktrace would not be logged.
