org.apache.jasper.JasperException: JBWEB004001: Unable to compile class for JSP

[Dinko Belchevski]

Hi,

I'm having troubles with HotSwapAgent (build from Git source, commit 145). We are using Java 8 with Jboss 7.0.0 GA. Immediately after Jboss restart everything works fine, but after some time (usually several hours) we are facing following issue:

If we disable HotSwapAgent everything is fine. It seems that HotSwapAgent locks some files and they cannot be moved. We don't need BrowserWeb to be monitored by HotSwapAgent, but we tried different ways to disable it per module and nothing works.

Here is the error from the agent itself:
