Hi Fabian, I fail to build java-1.8.0-openjdk on armv5. I get errors regarding gdb: + gdb -q /builddir/build/BUILD/java-1.8.0-openjdk-1.8.0.141-2.b16.el7.arm/openjdk/build/jdk8.build/images/j2sdk-image/bin/java + tee gdb.out Reading symbols from /builddir/build/BUILD/java-1.8.0-openjdk-1.8.0.141-2.b16.el7.arm/openjdk/build/jdk8.build/images/j2sdk-image/bin/java...done.

This is all related to a new section about gdb in the SPEC-file: # Make sure gdb can do a backtrace based on line numbers on libjvm.so gdb -q "$JAVA_HOME/bin/java" <<EOF | tee gdb.out handle SIGSEGV pass nostop noprint handle SIGILL pass nostop noprint set breakpoint pending on break javaCalls.cpp:1 commands 1 backtrace quit end run -version EOF grep 'JavaCallWrapper::JavaCallWrapper' gdb.out Now my question, does this build on armv7 ?
