Resolve multiple-applet deadlock issue in JNLPClassLoader
New lock used for synchronizing JNLPClassLoader#loadClass(String) to avoid
deadlock condition when multiple applets are being loaded simultaneously.
Regression test included.
* netx/net/sourceforge/jnlp/runtime/JNLPClassLoader.java: (loadClassLock)
private member for locking of loadClass method. (loadClass) synchronizes
using new lock rather than instance intrinsic lock to avoid RH976833
