I've used Inline::Java for 2 main projects in my $work: one is a wrapper around the Maven libraries to introspect POMs, the other is a long run daemon using an internal java library. I've found it to be extremely reliable. To help maintain performance, keep in mind the following:
1. use the JNI interface so that all Perl<->Java communication happens in the same process. the other mode runs a separate process and communicates over a unix socket. 2. more importantly, plan very carefully your calls (method calls, property lookups, object construction, etc.) from Perl to Java. I've found that the time to communicate even simple data can take much longer that the time taken to process that data (to much context switching). (2) for me was exemplified for me on wrapping our internal Java library. I was doing lots of back-and-forth. After implementing a Java-side layer that did the same calls I was doing from Perl, I saw a significant speed boost. Hope this helps.
