We'd recently migrated from Weblogic 11g to Tomcat 8/Java 8. We very quickly
found this to be a critical problem as well in highly concurrent environment.

Is there a use case were WebappClassLoader must not be parallel?
Is it an option to re-implement jdk1.7 method
java.lang.ClassLoader#getClassLoadingLock(String) directly in WebappClassLoader
for Tomcat7.

The performance hit would only occur during class loading. By the time a few
requests have been processed, class loading should have settled-down quite a
bit.
Some thoughts about performance:

Please consider not only the performance impact but also stability of web
application. I am seeing 2-10 sec pauses for all requests in my web application
caused by some bad code in just one request.

Oracle's public support has ended for Java 6 but other vendors may have
different policies and if you pay Oracle $ you can still get support, updates

The problem occurred in eclipse and context.xml was not loaded properly.
Right now everything works good.

The stack trace shows you aren't using parallel class loading. The lock is on
the ClassLoader rather than a class specific object.

Still not sure the problem is solved.
The problem tested in apache-tomcat-8.0.18 with ParallelWebappClassLoader

And apache-tomcat-7.0.35 has much better performance.

The partial stack trace is largely useless since it does not show what the
critical thread (http-bio-31680-exec-41) is doing.

The implementation of GlassFish "working" on JDK 6, is avoiding "systematic"
synchronization on the instance, and so that seems to have been enough to be
fast, see
