There is a lot of JAR filesystems for files under /proc. This looks really wrong.
There are class not found exceptions for other IDE classes as well, e.g. ClassNotFoundException: org.netbeans.modules.parsing.spi.indexing.support.IndexResult
I'd suggest to start NetBeans with a fresh user directory and if problems persist, reinstall NetBeans.
