we recently upgraded all our environments to java 1.7 and now the JfileUpload is having problems loading. It seems to be a security related issue (output from console log below)
Posts have suggested that it may be related to a firewall issue and suggests adding the command argument "-Djava.net.preferIPv4Stack=true", but that seems to only work some of the time. Rolling back to 1.6 is not an option, please advise on a fix as we are a licensed customer.

security issue with java 1.7Re: security issue with java 1.7Looks like there is a bug in JRE 1.7.0_45 when you run applet locally. Workaround is to reference applet in JNLP file. Sample solution for JFileUpload attached.
Re: security issue with java 1.7This issue does not occur anymore with JRE 1.7.0_51
