XML export error

[bittremieux]

I get the following error when PIA tries to write its XML output:

Could this be due to an outdated version of JAXB that's not compatible with my Java version? For example, see jakartaee/jaxb-api#78 and https://stackoverflow.com/a/43574427.

I'm using Java version 13.0.1, while the pom file seems to indicate a PRIDE version 1.0.22 of JAXB is used. Is this even the standard JAXB version number? If so, it seems a pretty old one and an update to JAXB version 2.4 seems useful to support current Java versions.

Yes, this is a JAXB incompatibility with new Java versions (new being >= 9).
Did you download the latest version or tried directly the GitHub version? If the version, could you please try the GitHub version. I had this problem before and at least for some versions it is fixed, but not released yet.

[bittremieux]

This was with version 1.3.10, the latest release available on here.

Do you mean to build the jar from master instead?

[julianu]

I just figured out the JAXB dependency was only in my private branch up to now. A new release was just added which should contain a fix for this.
Please let me know, whether this solves the issue.

[bittremieux]

Yes, the JAXB error is fixed for version 1.3.11. Thanks.
