NullPointerException in convertBlockCoverageToLineCoverageForClass (compiled JDK7, running JDK11)

See original GitHub issue

While moving the Java 7 / Android branch of my code from Travis to Azure Pipelines, I needed to update the Java runtime for PIT to JDK 11 to fix JVM crashes (see https://jaxenter.com/nobody-puts-java-container-139373.html for the probable reason), which due to various dependencies, meant updating PIT to version 1.4.7. I’m now getting:

Sorry, this does indeed look like something that I introduced in 1.4.7, although there was also another issue (which was causing the failure on 1.4.6). The changes in my fork issue-597 seem to resolve both issues - I will open a PR.

1.4.8 fixes the NPE, but gives me the same “duplicate class definition” error as 1.4.6. Since you said that was a separate bug, I’ve filed it as #613.
