FULL PRODUCT VERSION :
java version "1.9.0-ea"
Java(TM) SE Runtime Environment (build 1.9.0-ea-b78)
Java HotSpot(TM) 64-Bit Server VM (build 1.9.0-ea-b78, mixed mode)

ADDITIONAL OS VERSION INFORMATION :
Description: Ubuntu 14.04.3 LTS


A DESCRIPTION OF THE PROBLEM :
During the Automated testing of the Groovy language, there are test failures occuring like this:
*** Error in `/opt/jdk9-build/j2sdk-image/bin/java': double free or corruption (fasttop): 0x00007fae9c2ae780
The error occurs repeatedly, but not reliably in specific tests. So the same test sometimes fails, sometimes passes. The same tests do not fail in JDK6-JDK8.

Due to the nature of the error, it is difficult to give a simple example to reproduce.

One way to reproduce on the groovy 'master' branch is to run the command:
./gradlew :groovy-groovysh:test -Pindy=true --tests org.codehaus.groovy.tools.shell.*
This reliably produces the failure one or more times, though not in relation to a specific test.

Please advise how to proceed to provide more detailed information.

REGRESSION. Last worked in version 8u60

ADDITIONAL REGRESSION INFORMATION:
java version "1.9.0-ea"
Java(TM) SE Runtime Environment (build 1.9.0-ea-b78)

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
git clone git@github.com:apache/incubator-groovy.git
git checkout 8e9716256b95ee9a
cd incubator-groovy
./gradlew :groovy-groovysh:test -Pindy=true --tests org.codehaus.groovy.tools.shell.*

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
BUILD passes
ACTUAL -
Build fails, output shows instances of
*** Error in `/opt/jdk9-build/j2sdk-image/bin/java': double free or corruption (fasttop)

REPRODUCIBILITY :
This bug can be reproduced always.

CUSTOMER SUBMITTED WORKAROUND :
Since this symptom only appears in JDK9, we hope it will be fixed before a release.
