TLDSCanner is not loading system TLDs in Java 11.0.1

[bpcrao]

The system tlds are skipped in few scenarios
the only option is the class loader has to be URLClassLoader which is not the case is Java 11 and hence fails

Piranha uses a custom classloader, so it doesn't work with it either

I added the context attribute org.glassfish.wasp.useMultiJarScanAlgo which selects the more powerful scanner as of 566ac7d. I tested this with JDK 15 and the latest Piranha, and there it works now.

@bpcrao can you test if this also works for you know, if you're still interested in this after all this time.

Next to the more powerful scanner we could also provide an additional SPI for the scanning.
