'throw' caught by containing 'try' statement

Reports throw statements whose exceptions are always caught by containing try statements.

Using throw statements as a "goto" to change the local flow of control is confusing and results in poor performance.

Example:

  try {
    if (!Files.isDirectory(PROJECTS)) {
        throw new IllegalStateException("Directory not found."); // warning: 'throw' caught by containing 'try' statement
    }
    ...
  } catch (Exception e) {
      LOG.error("run failed");
  }
