This can be solved by looking for the compilation failure in case there is no main section -> the main has not been executed -> failure occurred during compilation

Even if we add another case in the future, I'd prefer to keep the current implementation stable by only adding another expression to the `if` branch. From:
`if (titles[i].equals("main") || titles[i].equals("shell")) {`
to:
`if (titles[i].equals("main") || titles[i].equals("shell") || titles[i].equals("compile")) {`

The comment:
> `// we are looking primarily for either a "main" section or a "shell" section in jtr log`

should be reworded to something that handles all current and future cases. For example:
> `// try to find and return first output from the following sequence of title names`

Nit: the previous commit touching this line (https://github.com/openjdk/jtreg/commit/8c105f2953edac0881819131f5f6836bda06ef25) introduced an `import java.util.Arrays;` statement which wasn't used back then. Can it be removed?
