The chart support included with Profound UI does not use Java. So unless you're integrating a separate java-driven chart engine, there shouldn't be a problem with charts.
Profound UI only uses uses Java for PC Integration, which consists of these two things:
1) Running PC commands (via either the STRPCCMD from a Grnie session, or the runPCCommand() API from either Genie or Rich Display)
2) Copying data to the Windows clipboard with the copyToClipboard() API.
We have a solution for #1, which is available for download from our web site. It is called the "PC Command Listener", it's a windows program that needs to be installed on all PCs that will run commands sent over from the IBM i. It requires Profound UI 5.2.0 or newer, and needs to be enabled with the following configuration option:

We don't currently have a solution for #2. I don't think very many customers use the copyToClipboard() API.
