Hi Chris,

I have forwarded this bug report upstream and received a private e-mail from Steven Rubin,
apparently the only active developer of Electric. He stated that Electric builds fine with
the Oracle JDK. He suggested to change the following line in
com/sun/electric/tool/user/ui/JobTree.java from

public static class JobTreeNode implements TreeNode

to be

public static class JobTreeNode extends DefaultMutableTreeNode

Unfortunately that didn't fix the issue for me. When I reported my findings to him, he indicated
that it would be better to remove Electric from Debian then...

Do you think using casts would be a viable option with those "terrible Swing" issues?

Regards,

Markus
