[BUG] cuvs-java com.nvidia.cuvs.CagraRandomizedTest.testResultsTopKWithRandomValues test fails intermittently

Describe the bug
cuvs-java test fails intermittently, e.g.

[ERROR] Tests run: 1, Failures: 1, Errors: 0, Skipped: 0, Time elapsed: 2.031 s <<< FAILURE! -- in com.nvidia.cuvs.CagraRandomizedTest
[ERROR] com.nvidia.cuvs.CagraRandomizedTest.testResultsTopKWithRandomValues -- Time elapsed: 2.031 s <<< FAILURE!

Steps/Code to reproduce bug
It's not clear if setting the random seed (-Dtests.seed) actually improves reproducibility.

./build java
cd java/cuvs-java
mvn -Dtests.seed=93DF604C314D221A test

Expected behavior
The test passes successfully every time.

Environment details (please complete the following information):

• Environment location: [Bare-metal, Docker, Cloud(specify cloud provider)]
  • AWS g4dn.2xlarge, Ubuntu 22.04 + cuda 12.6
• Method of RAFT install: [conda, Docker, or from source]
  • If method of install is [Docker], provide docker pull & docker run commands used

set the JAVA_HOME env variable to JDK 22

JAVA_HOME=/home/ubuntu/binaries/jdk-22.0.2/

Additional context
This fails in branch-25.02, with the commit that added the java-api:

commit 4ca47c92b03856e7d4ae328aabf6ee3e853a137e (...

Initial cut for a cuVS Java API (#450)
    
A Java API for cuVS for easy integration into Apache Lucene or other Java based projects.

Start in java/cuvs-java with com.nvidia.cuvs.CagraRandomizedTest.testResultsTopKWithRandomValues and the failure path in CuVSTestCase.compareResults. Build with ./build java, then run mvn -Dtests.seed=93DF604C314D221A test from java/cuvs-java on the documented CUDA environment. Done means the randomized test passes reliably, including with the reported seed.
