Subject Re: [jira] Commented: (UIMA-1652) Cannot hot-install a PEAR twice
Date Thu, 05 Nov 2009 17:53:00 GMT
Just like with the bootstrap loader thingy, this will fail
when run under a security context that doesn't allow futzing
with loaded classes (which, when you think about it, really
shouldn't be allowed anyway).  Before we add this, I'd like
to see it tested in applets and application servers to make
sure it does no harm.  For the bootstrap loader this doesn't
matter, for the UIMAClassLoader it matters very much.  (I
have no idea if UIMA even runs in applets, for that matter).
