DO NOT REPLY [Bug 49240] New: Error thrown during detection of ServletContainerInitializer's

https://issues.apache.org/bugzilla/show_bug.cgi?id=49240

           Summary: Error thrown during detection of
                    ServletContainerInitializer's
           Product: Tomcat 7
           Version: unspecified
          Platform: All
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
        AssignedTo: dev@tomcat.apache.org
        ReportedBy: bugzilla@pidster.com


ContextConfig.checkHandlesTypes() throws a NoClassDefFoundError, which isn't
caught, when the class being analysed is initialised if the class, or a class
that it references(?), is not present in the classpath.

E.g. When a mysql connector/j jar (v5.x) is scanned, an attempt to load the
following class occurs: com.mchange.v2.c3p0.QueryConnectionTester

java.lang.NoClassDefFoundError: com/mchange/v2/c3p0/QueryConnectionTester
    at java.lang.ClassLoader.defineClass1(Native Method)
    at java.lang.ClassLoader.defineClass(ClassLoader.java:698)
    at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:124)
    at java.net.URLClassLoader.defineClass(URLClassLoader.java:260)
    at java.net.URLClassLoader.access$000(URLClassLoader.java:56)
    at java.net.URLClassLoader$1.run(URLClassLoader.java:195)
    at java.security.AccessController.doPrivileged(Native Method)
    at java.net.URLClassLoader.findClass(URLClassLoader.java:188)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:315)
    at java.lang.ClassLoader.loadClass(ClassLoader.java:250)
    at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:398)
    at java.lang.Class.forName0(Native Method)
    at java.lang.Class.forName(Class.java:247)

Also Class.forName is used here, referencing the WebappClassLoader, instead of
calling WebappClassLoader.loadClass() directly.

Fixes thrown Error during ServletContainerInitializer's

return if an exception is thrown, use the webapp classloader directly

Fixes thrown Error during SCI detection

Patch doesn't need to warn for every NoClassDefFoundError, debug is a better
logging level.
