Incorrect resolution of SPDX license expression

Issue Type: Bug
Issue Description:

I was looking at [https://clearlydefined.io/definitions/git/github/eclipse-ee4j/mail/4c092797479f6fb05576e723a6855a7e116ed027](https://clearlydefined.io/definitions/git/github/eclipse-ee4j/mail/4c092797479f6fb05576e723a6855a7e116ed027) and noticed that there are lots of cases where files with SPDX: "EPL-2.0 OR GPL-2.0 WITH Classpath-exception-2.0" resolve to "EPL-2.0 OR NOASSERTION".

One random example of such a case is the file https://github.com/eclipse-ee4j/mail/blob/4c092797479f6fb05576e723a6855a7e116ed027/gimap/src/main/java/com/sun/mail/gimap/protocol/GmailProtocol.java.

If you look at line 30899 in the raw data of the definition, looks like the tools have got the license expression correct for this file: "epl-2.0 OR gpl-2.0 WITH classpath-exception-2.0".

However, when you look under "Files", the reported license for the same file appears as "EPL-2.0 OR NOASSERTION".


It looks to be that ScanCode is detecting the license correctly, but the same information is not showing in ClearlyDefined.

Thanks,

Brian
