A DESCRIPTION OF THE PROBLEM :
We discovered a memory leak when using the apache/pdfbox library. After investigation, we initially determined that the root cause was an off-heap memory leak in sun.java2d.cmm.lcms.LCMS#createNativeTransform() function.
I think it's same as https://bugs.openjdk.org/browse/JDK-8181183.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
run following code long time, and check the RES with following command `loop=0; while [ "$loop" -lt 100 ]; do date ; top -b -n 1 -p <pid> | grep java ; sleep 1800; done`



EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
the pid's RES should be same for long time.
ACTUAL -
the RES memory continues to grow
