Issue with Java 6 Update 18 and WebApp
First, some background.
We developed a Library Management System called Metamarc and use Java WebApp for the Circulation module.
This has been running successfully since Java 1.3 and up to Java 6 Update 17.
However, since Java 6 Update 18, the module does not work correctly, as illustrated in the attached document with screen captures of the correct operation with Java 6 Update 17 and the in-correct operation with Java 6 Update 18 and later.
We have been trying some some time to get an answer to this problem, but the purchase of Sun by Oracle has not helped.
We would be pleased to receive information on the changes in Java 6 Update 18 (and beyond) that could cause our WebApp to malfunction.
Thank you for any assistance.
Re: Issue with Java 6 Update 18 and WebApp
If you're trying to report or investigate a bug, the best way to do it is to boil it down to an SSCCE that demonstrates the problem in as few lines as possible. Every bug report contains one. Post it here and we can help you figure out what's going on, or we can point you to the official bug report site (where it may already have received a response).
Out of curiosity, have you tried it with more recent updates, or even Java 7? Java 6u18 seems pretty old. I just checked, and my system is at 6u26.
