Lucene test failures with 32 bit JDK 9b78, Server compiler

FULL PRODUCT VERSION :

A DESCRIPTION OF THE PROBLEM :
During our ongong stress tests (running Apache Lucene) on JDK9 preview builds, we discovered the following bug, which makes it impossible to use Apache Lucene/Solr/Elasticsearch with JDK9:

We are running the Lucene Core Testsuite of the recently released Lucene 5.3.0 Tarball. The tests should pass on any current JVM. Unfortunetely under the following configurations this fails:

- It does not fail with 64 bits (I tried like 20 runs of test suite).
- It does not fail with 32 bits and "-client" (I also tried 20 runs).
- It fails ASAP on 32 bits (in the first few Lucene tests with messages about random NPEs or failed assertions) with: "-server -Xbatch -XX:+TieredCompilation"
- It also fails on 32 bits, but takes longer (like 60 tests of the suite ran): "-server -Xbatch-XX:-TieredCompilation")

THE PROBLEM WAS REPRODUCIBLE WITH -Xint FLAG: No

THE PROBLEM WAS REPRODUCIBLE WITH -server FLAG: Yes

REGRESSION. Last worked in version 8u60

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
thetaphi@serv1:~$ wget http://www.apache.org/dist/lucene/java/5.3.0/lucene-5.3.0-src.tgz
thetaphi@serv1:~$ tar xf lucene-5.3.0-src.tgz
thetaphi@serv1:~$ cd lucene-5.3.0/
thetaphi@serv1:~/lucene-5.3.0$ ant ivy-bootstrap
thetaphi@serv1:~/lucene-5.3.0$ cd core/

thetaphi@serv1:~/lucene-5.3.0/core$ ant test -Dtests.jvms=1 -Dargs='-client'
(passes)

thetaphi@serv1:~/lucene-5.3.0/core$ ant test -Dtests.jvms=1 -Dargs='-server -Xbatch -XX:+TieredCompilation'
(fails after running a few tests)

thetaphi@serv1:~/lucene-5.3.0/core$ ant test -Dtests.jvms=1 -Dargs='-server -Xbatch -XX:-TieredCompilation'
(fails bit later, sometimes whole suite passes)

EXPECTED VERSUS ACTUAL BEHAVIOR :
Lucene Testsuite should pass.
ERROR MESSAGES/STACK TRACES THAT OCCUR :
Various test failures:
- NPE
- test assertions fail (e.g. number of returned Lucene search results)
- also Java assertions fail

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
This is impossible for this case, the bug is only triggered on stress testing the whole test suite.
---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Use -client compiler or switch to 64 bit JVM.
