Project Lilliput adds 2 additional CDS archives, classes_coh.jsa and classes_nocoops_coh.jsa. The jlink CDSPlugin.java file only generates the first two archives. This causes failures in the CDSPluginTest.java.

This is fixed in the latest commit to the CompactObjectHeaders PR.

[~rkennke] Try this patch to the test (better than the last thing I posted). Thanks to [~ccheung] for his slack advice. + WhiteBox wb = WhiteBox.getWhiteBox(); + boolean COMPACT_HEADERS = + Platform.is64bit() && wb.getBooleanVMFlag("UseCompactObjectHeaders") && wb.isDefaultVMFlag("UseCompactObjectHeaders"); + + String suffix = COMPACT_HEADERS ? "_coh.jsa" : ".jsa"; +

It doesn't look like a fix for this issue to me. Note that the change in that patch fixed an earlier issue. It solved the problem when you have UseCompactObjectHeader on by default in the code. This bug talks about another issue that arise when you set UseCompactObjectHeader on the command line.

https://github.com/openjdk/lilliput-jdk21u/pull/36/files Is this the fix to this in one of the Lilliput repos? Is this going to be the fix in the PR?

My understanding was that there is an incompatibility between the shared archive being used and the use of the +UseCOH flag.

I'm confused what we're looking for here. Maybe [~matsaave] has figured it out. I'll ask him.
