Description zzambers 2021-09-14 13:28:27 UTC 
Openjdk's (java-17-openjdk) libfontmanager.so has missing dependency on harfbuzz library on rhel-8.5. As a result several of our tests throw UnsatisfiedLinkError:

java.lang.UnsatisfiedLinkError: /mnt/ramdisk/java-17-openjdk-17.0.0.0.33-0.5.ea.el8.x86_64/jdk/lib/libfontmanager.so: /mnt/ramdisk/java-17-openjdk-17.0.0.0.33-0.5.ea.el8.x86_64/jdk/lib/libfontmanager.so: undefined symbol: hb_font_funcs_set_glyph_h_advance_func
...


ldd /usr/lib/jvm/java-17-openjdk-17.0.0.0.33-0.5.ea.el8.x86_64/lib/libfontmanager.so | grep harfbuzz

(prints nothing)


Interestingly, rhel-9 is not affected by this issue:
ldd /usr/lib/jvm/java-17-openjdk-17.0.0.0.33-0.5.ea.el9.x86_64/lib/libfontmanager.so  | grep harfbuzz
	libharfbuzz.so.0 => /lib64/libharfbuzz.so.0 (0x00007effdc18d000)

Just as experiment I tried to patch libfontmanager.so by adding dependency on libharfbuzz.so.0, using patchELF (see [1]) in rhel-8 VM. It fixed this issue.

Comment 3 Andrew John Hughes 2021-09-18 02:56:23 UTC 
This was JDK-8272332; a typo in JDK-8272332 meant the HarfBuzz linker flags were never added and the practice of allowing undefined symbols meant this didn't show up during the build.
Comment 8 bernhard.schuhmann 2021-10-07 13:46:37 UTC 
Rhel-7 is also affected, in my case it's /usr/lib/jvm/java-17-openjdk-17.0.0.0.35-1.rolling.el7.x86_64/lib/libfontmanager.so, and undefined symbol: hb_font_funcs_set_glyph_v_kerning_func.

Thanks, @zzambers for the workaround!

Hmm, it indeed also affects EPEL7. I have made clone of this bug for java-latest-openjdk/epel7:
