Turns out I'm stuck on Java 1.4.2_16, but this feature was only added to Java in 1.5 :'(

Compile time failure:
(I've trimmed out quite a lot of the script to be succinct)
Important bits: 
use Inline Java  => <<'END_OF_JAVA'
--snip--
Map<String,Long> myMap = new Map<String,Long>();
--snip--

[download]
Then when I check it: 
perl -c test.pl
--snip--

The error message was:
test_pl_185a.java:31: <identifier> expected
  Map<String,Long> myMap = new Map<String,Long>();
     ^
1 error
--snip--

[download]
The program runs perfectly with just that Map removed (I'm adding a new feature)

What am I doing wrong?
