Comment 1 Thomas Leroy 2023-06-15 08:43:09 UTC

The issue has been created in the jtidy fork trajano/jtidy as far as I understand, but that might also affect sourceforge jtidy

Comment 2 Thomas Leroy 2023-06-21 08:14:10 UTC

Tracking jtidy as affected:
- SUSE:SLE-12:Update
- SUSE:SLE-15-SP2:Update
- SUSE:SLE-15:Update
- SUSE:ALP:Source:Standard:1.0

Upstream project looks dead, not sure maintainers will provide a fix

Comment 5 David Anes 2023-07-17 06:26:37 UTC

Hi Stoyan and Gus,

The following two commits fix the issue:

* https://github.com/jtidy/jtidy/commit/fc011d34ea3f2cb1395e8443154b31f690466b19
* https://github.com/jtidy/jtidy/commit/67a39369b6f9837a4273d0315b0c5ac7e7eb2905

I didn't evaluate how much effort is to fix all codestreams, but let me know if you need help Gus.

Comment 11 Gus Kenion 2023-07-26 11:14:08 UTC

Created a patch based on fix from github project jtidy/jtidy. Submitted change requests for SLE-12, SLE-12-SP2, SLE-15, and ALP.  Submitted request in Factory repo to replace existing upstream with github project jtidy/jtidy.  Discussion of the latter is ongoing.  Aforementioned patch fixes were all accepted.

Comment 12 Gus Kenion 2023-07-28 14:26:18 UTC

Patch change requests accepted in SLE-12, SLE-12-SP2, SLE-15, and ALP.  Version upgrade request accepted in Factory.
