Hello,
In some rare scenarios , we get this exception when we update records .
java.lang.NullPointerException: null
at
org.apache.ignite.internal.binary.builder.BinaryBuilderReader.<init>(BinaryBuilderReader.java:72)
~[ignite-core-2.8.1.jar:2.8.1]
at
org.apache.ignite.internal.binary.builder.BinaryObjectBuilderImpl.<init>(BinaryObjectBuilderImpl.java:122)
~[ignite-core-2.8.1.jar:2.8.1]
at
org.apache.ignite.internal.binary.builder.BinaryObjectBuilderImpl.wrap(BinaryObjectBuilderImpl.java:617)
~[ignite-core-2.8.1.jar:2.8.1]
at
org.apache.ignite.internal.binary.BinaryObjectExImpl.toBuilder(BinaryObjectExImpl.java:159)

at
com.company.project.projectname.helper.ProjectCacheEntryBinaryObjectProcessor.process(ProjectCacheEntryBinaryObjectProcessor.java:34)
~[dao-2.9.14.jar:?]
===================
As shown, the exception happens at this point in the project code :
at
org.apache.ignite.internal.binary.BinaryObjectExImpl.toBuilder(BinaryObjectExImpl.java:159)
~[ignite-core-2.8.1.jar:2.8.1]
at
com.company.project.projectname.helper.CacheEntryBinaryObjectProcessor.process(ProjectCacheEntryBinaryObjectProcessor.java:134)
~[dao-2.9.14.jar:?]
Line 134 of ProjectCacheEntryBinaryObjectProcessor says :
132: BinaryObject currentValueObject = mutableEntry.getValue();
133: if (currentValueObject !=null) {
134: binaryObjectBuilder = currentValueObject.toBuilder();
================
The exception happens at this position in the BinaryBuilderReader.java
reader = new BinaryReaderExImpl(ctx,
BinaryHeapInputStream.create(arr, pos),
ctx.configuration().getClassLoader(),
false);
=====================
The exception log in the try/catch prints the mutableentry.getValue as :
2020-09-30T16:58:23,989 ERROR
c.c.p.c.h.ProjectCacheEntryBinaryObjectProcessor [sys-stripe-12-#13]: CACHE

[idHash=219577898, hash=-978873982,
NAME=xxx],MutableEntry.valueBinaryObjectImpl [arr= true, ctx=false, start=0]
====================
Please note we dont get this exception always. Kindly request your guidance
on how to find out the root cause for this exception.
regards,
Veena.
