Adam Sotona has updated the pull request incrementally with five additional commits since the last revision:

 - fixed ModuleDescriptorTest::testReadsWithBadPackageFinder to use Classfile API directly to generate modules descriptor without ModulePackagesAttribute
 - ModuleInfoWriter converted to support invalid module names and emit ModulePackagesAttribute if packages are provided
 - fixed Classfile API tests
 - added ModuleAttribute::of(ModuleEntry, Consumer<ModuleAttributeBuilder>)
 - removed obsolete Classfile.buildModule method argument List<PackageDesc> and obsolete method overrides
