Add exception in LicenseFactoryInfo to catch throw in parseSPDXLicenseStringCompatV2 method

Spdx-Java-Library/src/main/java/org/spdx/library/LicenseInfoFactory.java

Line 114 in 65c57fd

throw new InvalidLicenseStringException("Unexpected SPDX error parsing license string");

Wouldn't it be better to pass the original exception to InvalidLicenseStringException so that the root cause is shown in the stack trace?

Yeah it looks like an oversight in just that one line of code. Would you be interested in submitting a PR for this?

[gabetrau]

Yeah I can
