I have located the source of the bug and have a patch to fix it. The cause is the use of dh_strip_nondeterminism late in the build process. This reorganises the jmod files, which in turn changes their SHA256 checksums. This would not be a problem, except that the checksums are saved in java.base.jmod *before* the use of dh_strip_nondeterminism. Performing this stripping immediately after each jmod file is created results in the checksums being consistent throughout. To do this: * add the attached patch to debian/patches (and to the quilt patch series); this calls strip-nondeterminism whenever a jmod file is created * add the strip-nondeterminism package as a Build-Depends * optionally add "-Xjmods" to the dh_strip_nondeterminism call on line 1781 (or thereabouts) of debian/rules (within the binary-arch target) - this is optional, because applying strip-nondeterminism a second time should not change anything. Of course, to make the patch more generally applicable, one could add a check for strip-nondeterminism into the configure script, etc., but for a debian-specific build, that does not seem to be necessary. Incidentally, the check for the existence of dh_strip_nondeterminism in debian/rules is unnecessary, as debhelper Depends on dh-strip-nondeterminism, and has done since version 9.20151004. Best wishes, Julian
