Digging further I should say that
1. There is, indeed, lock on the ClassLoader in the native code.
2. There is "experimental" option to turn off that locking. E.g., described
here:
http://underlap.blogspot.com/2006/11/experimental-fix-for-sunbug-4670071.html
and thus Tomcat is not the first one to run into such an issue.
3. Evaluation part of
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4670071
mentions API change to allow parallel classloading, and API change actually
means that it will be no sooner than JDK7. See
http://java.sun.com/javase/7/docs/api/java/lang/ClassLoader.html
methods registerAsParallelCapable() and getClassLoadingLock(String)
While I was evaluating this, several comments were added to bug 48694,
especially attachment 25124, which is another sample of a deadlock (in that
case JRE is 1.6.0_13).
