            Bug ID: 34475
           Summary: detect incompatible java compiler during autoconf
           Product: systemtap
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: releng
          Assignee: systemtap at sourceware dot org
          Reporter: fche at redhat dot com
  Target Milestone: ---

On riscv, java-25-openjdk-* appears incapable of compiling our byteman-related
code:

make[3]: Entering directory
'/home/builder/worker/systemtap-fedrawhide-riscv64/stap-build/java'
javac -d . org/systemtap/byteman/helper/HelperSDT.java
Error occurred during initialization of VM
Unsupported satp mode: SV57. Only satp modes up to sv48 are supported for now.
make[3]: Leaving directory
'/home/builder/worker/systemtap-fedrawhide-riscv64/stap-build/java'
make[3]: *** [Makefile:774: org/systemtap/byteman/helper/HelperSDT.class] Error
1
make[3]: *** Waiting for unfinished jobs....

The autoconf logic should include this sort of check before committing to build
java support.
