Hoss Man commented on LUCENE-5471:
----------------------------------
bq. Even more puzzling, the program works if I first run it without a
SecurityManager, then install a SecurityManager, then re-run the program, all
within the lifetime of a single JVM.
I suspect this is because of when/how SPI is used - if the codec is resolved
before you load the security manager, then that info is still available in
NamedSPILoader.
if you did a NamedSPILoader.reload() on your classloader after activating the
SecurityManager, you'd probably see the same problem no matter what.
bq. I think its a bug in your securitymanager config (e.g. you are missing
reflectpermission or something really necessary).
yeah ... w/o showing us what security manager you are using, it's hard to guess
what the specific problem might be.
that said: it's strange that you got an IllegalArgumentException from
NamedSPILoader instead of a SecurityException ... i can't think of any
(legitimate) reason why that should have happened, unless we're swallowing
RuntimeExceptions in the SPI Loader code?

> I see the following error when I run Lucene 4.5.0 under a java
