Description Mark Thomas 2020-01-25 08:25:37 UTC
The custom service loader implementation used by the EL API is incomplete. It does not skip comments causing it to use a comment line as a class name. This means it often fails to load a valid EL implementation present on the class path.

I suspect the issues are not limited to comment handling but I haven't dug further.

Switching to using ServiceLoader rather than a custom implementation looks to be the best solution.
