Why is this an issue?
Since Java 7 it has been possible to catch multiple exceptions at once. Therefore, when multiple catch blocks have the same code, they
should be combined for better readability.
Note that this rule is automatically disabled when the project’s sonar.java.source is lower than 7.
Noncompliant code example
catch (IOException e) {
  doCleanup();
  logger.log(e);
}
catch (SQLException e) {  // Noncompliant
  doCleanup();
  logger.log(e);
}
catch (TimeoutException e) {  // Compliant; block contents are different
  doCleanup();
  throw e;
}

Compliant solution
catch (IOException|SQLException e) {
  doCleanup();
  logger.log(e);
}
catch (TimeoutException e) {
  doCleanup();
  throw e;
}
