[jruby-dev] [jira] (JRUBY-6977) try/rescue catchall doesn't catch Java exceptions

Wed, 31 Oct 2012 03:30:23 -0700

Issue Type: Bug Bug
Affects Versions: JRuby 1.7.0
Assignee: Unassigned
Components: Core Classes/Modules
Created: 31/Oct/12 5:30 AM
Description:

The try/rescue 'catch-all' definition doesn't catch java Exceptions.

For example in the following example the second catch block catches the error, instead of the general "rescue => e" block. 

begin
  java.lang.Integer.parseInt("")
rescue => e
  $stderr.puts "catch all #{e.class}"
rescue java.lang.Throwable => e
  $stderr.puts "java'ish catchall #{e.class}"
end

# prints 
## java'ish catchall Java::JavaLang::NumberFormatException

A workaround seems to be explicitly catch Throwable.
