Hi Jacco,
So two things :
I tried to build it against 7.3.1611+updates and then I confirm what
you're seeing with gdb
(https://armv7.dev.centos.org/rpmbuild/c71611-updates-1/19786-java-1.8.0-openjdk-1.8.0.131-11.b12.el7/armv7hl/build.log)
:
+ gdb -q

es/j2sdk-image/bin/java

A debugging session is active.
Inferior 1 [process 4802] will be killed.
Quit anyway? (y or n) [answered Y; input not from terminal]
+ grep JavaCallWrapper::JavaCallWrapper gdb.out
RPM build errors:
error: Bad exit status from /var/tmp/rpm-tmp.LcfCwP (%check)
Bad exit status from /var/tmp/rpm-tmp.LcfCwP (%check)
Child return code was: 1
EXCEPTION: [Error()]
I also checked the other log
(https://armv7.dev.centos.org/rpmbuild/c71708-pass-1/19329-java-1.8.0-openjdk-1.8.0.131-11.b12.el7/armv7hl/build.log)
about resources.jar file missing, when it finds 1.7 and I exploded the
rpm through rpm2cpio to verify the content and yes, there is a
permission issue in the -headless package :
/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.141-2.6.10.5.el7.arm/jre/lib/resources.jar
is 600 so probably not readable by mock itself (argh)
Have now to investigate if the perm issue is due to that package build,
or if the .spec needs some changes to force better permissions.
