To me this really looks like there's some value in the keys/values which keeps perl from outputting the whole page.

A) You could try to print only the keys and see which one comes after 'PROCESS.javaloc.Menus1'. This ~should~ print all 63 keys.

Then you can change 'sort keys' into 'reverse sort keys' and if there's only one malformed key/value then you should end up with 46 lines of output. If there are less then that, then there are more then one bogus keys/values.

B) Can perl write files to the filesystem? Normally the answer is yes, but you seem to be working on a webserver and who knows how it's configured. (Maybe someone really nailed it down and prevents write access to the filesystem via a SELINUX policy...)

If you can write, then you could print your results to a file and check the contents of that file. At least you don't have to worry about proper HTML entity escaping, browser bugs and possible buffering issues.

C) Do you have access to the webserver error log? If not: Get familiar with eval and catching exceptions and try to catch the error message, why perl terminates abnormally. Hint: Try::Tiny is really nice. The documentation also explains what can go wrong with eval. But pay attention to the trailing semicolon 'try {} catch {};' <--- Strange stuff happens if you ommit it.
