Description

Running test with coverage threw a NullPointerException:

SEVERE [global]
java.lang.NullPointerException
at org.netbeans.modules.gsf.codecoverage.CoverageReportTopComponent.updateData(CoverageReportTopComponent.java:367)

Tests are all passed, but coverage is not shown.

Now using mouse right button on the project -> code coverage -> show report

results in a NPE with description: NullPointerException: Cannot invoke "org.netbeans.modules.gsf.codecoverage.api.FileCoverageSummary.getLineCount()" because "summary" is null
