Generate features not called after successful compile

[turkeylurkey]

Usually the generate features task is called after Java code compiles successfully. But if Java code fails to compile twice in a row and then you fix the error and it compiles successfully then generate features is not called. It could also be that generate features is not called on an intermittent basis.

Use the demo-devmode project and start dev mode normally: gradle libertyDev
Next, modify SystemLivenessCheck.java to remove a semicolon to cause a syntax error and save. LGP reports Source compilation had errors. Remove another ; and save, same message. Correct both syntax errors and save again. Even though dev mode prints the message Source compilation was successful the generate features task does not run.

N.B. This affects one of the integration tests. Find this issue number in DevTest.groovy and restore the assertions.
