Hi,
I've put a new FPC JVM snapshot online (corresponding to svn r19598 of the
jvmbackend branch), linked from http://wiki.freepascal.org/FPC_JVM
Changes since the previous snapshot include:
* the compiler will now implicitly convert between all Pascal string types and
JLString (java.lang.String)
* most, if not all, previously missing string helpers have been added to the
system unit for all string types (insert, delete, pos, ...)
* several fillchar overloads for use on arrays have been added to the system
unit
* generics now work
* the compiler will now generate a constructor that takes an (automatically generated)
interface for all (also automatically generated) classes that are used to implement
"procedure of object" procedure variables. This allows them to be used much
more easily and naturally from Java code
* support for pchar, including typecasting an ansistring to pchar and indexing
it like on native platforms (with read/write capabilities). Note that this does
not work for unicodestring and pwidechar due to unicodestring mapping to
java.lang.String, which is both opaque and immutable
* exceptions raised in invocations of virtual class methods and procedure
variables are now properly propagated to the caller
* {$VARPARACOPYOUTCHECK+/-} / -Cv switch to enable checking var-parameters (and
to a limited extent also out-parameters) on the JVM target for changes to the
value passed as var-parameter during the function call (because they are
handled via copy-in/copy-out, this may indicate unexpected bahviour later on).
Note that this code has not been synchronized with FPC svn trunk recently. Even
though it's version 2.7.1, it dates from before the cpstrnew merge. I'm waiting
for those changes to completely settle down before updating the JVM backend
branch with them.

Interesting.
1) {$modeswitch unicodestrings} plus cpstring = nearly full string
compatibility with delphi.
2) Nested routines implementation for JVM is very similar to closures. I
think it could be easily advanced to complete crossplatform closure
implementation.
I`m wating merging to trunk )
