[Pljava-dev] Solaris and -Xusealtsigs [Was: Re: Need help on Pljava]

I am running PL/Java on Solaris 9 SPARC, and I have seen the issue
before. The fix is to just follow what the error message tells you
to do.

With Java 5 I have the following in my postgresql.conf file:

pljava.vmoptions = '-Xms8M -Xmx8M -XX:+UseAltSigns'

It works with absolutely no issues.
