A DESCRIPTION OF THE PROBLEM :
This bug-report is created in response to the Quality Outreach effort on request from Rory from the OpenJDK Quality Group and dalibor.topic@oracle.com.

When compiling Apache POI using the Java 9 early access version I see unit-tests fail with "java.lang.ArrayIndexOutOfBoundsException at sun.font.ExtendedTextSourceLabel.createCharinfo()" whereas they run fine in previous versions of Java (at least 6, 7 and 8).

Probably related bugs (Rory asked to report a new one nevertheless): https://bugs.openjdk.java.net/browse/JDK-8151725, https://bugs.openjdk.java.net/browse/JDK-8145542, https://bugs.openjdk.java.net/browse/JDK-8041480

ant \
    -Duser.language=en \
    -Duser.country=US \
    -Dmaxpermsize=-Dthis.is.a.dummy=true \
-Djava.locale.providers=JRE,CLDR \

-Dhalt.on.test.failure=false \
      compile-ooxml-lite

The compile output will show the failing tests


EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Compilation and execution of unit-tests should run fine.
ACTUAL -
