Cannot build with Tycho due to SqlJet Environment

[dorothy-agilemind]

Hello,
In the MANIFEST.MF of the osgi plugin org.tmatesoft.sqljet (which is packaged in the org.tmatesoft.svnkit Eclipse feature), there is an incorrect Bundle-ExecutionEnvironment.
The MANIFEST.MF of latest versions states

Bundle-RequiredExecutionEnvironment: JavaSE-1.5

whereas it should state J2SE-1.5 according to https://docs.osgi.org/reference/eenames.html
This was correct in the SQLJet 1.1.10 brought by SVNKit 1.8.5, but has regressed since then.

The unfortunate consequence is that one can not use SVNKit in a Tycho build, or it will fail with

org.apache.maven.InternalErrorException: Internal error: org.eclipse.tycho.core.osgitools.OsgiManifestParserException: Exception parsing OSGi MANIFEST /var/lib/jenkins/.m2/repository/p2/osgi/bundle/org.tmatesoft.sqljet/1.1.13.r1341/org.tmatesoft.sqljet-1.1.13.r1341.jar!/META-INF/MANIFEST.MF: Unknown OSGi execution environment: ‘JavaSE-1.5’

Would it be possible to fix it back to J2SE-1.5, or to consider upgrading it to JavaSE-1.6 (same as org.tmatesoft.svnkit) instead ?
Thanks in advance.

We are just a downstream consumer of this library. It comes from https://svnkit.com

The last few years they have been less responsive about fixing things but it would not hurt to try to post a bug report to them. If they would just publish a p2 repository we could just pull directly from them. In the past I have given them this suggestion and showed them how to do it.

For the record, there is a thread in the SVNkit forum about them not publishing a p2 repository: https://support.tmatesoft.com/t/no-repository-found-at-http-eclipse-svnkit-com-1-10-x/2388

That being said, the use of JavaSE-1.5 rather than J2SE-1.5 is discussed in eclipse-tycho/tycho#98, too, although I am not 100% sure whether this is a problem with the SVNKit headers or not. The OSGi spec is a bit vague.

Turns out that Tycho is correct and that SVNKit (or rather SQLJet) contains an invalid Bundle-RequiredExecutionEnvironment header. I have reported this upstream already.
