PR description

This PR set the configuration option tx-pool-enable-balance-check=true by default.
This ensure that in the prioritized layer of the txpool only pending tx for which the sender has enough balance to pay are kept, otherwise they will be demoted to the ready layer, waiting for a possible future sender balance change. This helps keeping the prioritized layer free of non executable pending txs.

The change has not any effect on the node performance, as seen by running it for some days, when compared with control nodes.

* Add MULMOD to EVMv2 (#10168)

- Add MulModOperationV2, tests and benchmarks
- Rename c -> m in benchmarks following (a * b) % m formula
- Add MulModOperationV2Test covering stack management and underflow

Tests verify correct stack depth reduction (3→1), result placement, zero-modulus special case, cross-limb arithmetic, and that underflow with 0 or 2 items returns INSUFFICIENT_STACK_ITEMS without mutating the stack.

* Enable NullAway static null-safety analysis for util module (#10046)

* Migrate JSR305 nullness annotations to JSpecify

- Replace javax.annotation.Nullable and javax.annotation.CheckForNull with org.jspecify.annotations.Nullable across 18 Java files
- Update platform constraint to org.jspecify:jspecify:1.0.0
- Replace compileOnly com.google.code.findbugs:jsr305 with compileOnly org.jspecify:jspecify in affected modules

* feat(util): enable NullAway with comprehensive nullability fixes

- Add NullAway 0.12.4 to util errorprone dependencies
- Annotate nullable fields/returns in 6 util classes with @nullable
- Fix nullable dereferences: RollingFileWriter, StackTraceMatchFilter, PlatformDetector
- Enable NullAway:ERROR for util main compile, OFF for tests
- Add optional CI job (run-nullaway label) for gradual monitoring
- All util compilation passes with NullAway ERROR by default

Fixes:
  - MemoryBoundCache: mark getIfPresent() return as @nullable
  - ExceptionUtils: annotate rootCause() for nullable input/output
  - RollingFileWriter: guard Path.getParent() null dereference
  - PlatformDetector: make static fields @nullable, add fallback to UNKNOWN

* chroe: Add jspecify compileOnly dependency

Add org.jspecify:jspecify as a compileOnly dependency to util/build.gradle. This brings JSpecify annotations into the module for static nullness/type-checking without introducing a runtime dependency.

* feat: Use shortVersion() and improve StackTraceMatchFilter

Update acceptance tests to call BesuVersionUtils.shortVersion() directly instead of using orElse("unknown"). In StackTraceMatchFilter, mark the Throwable parameter as @nullable and simplify toString() to return stackContains directly. These changes clarify nullability and streamline version usage/representation.

* docs: Fix Javadoc reference for UNKNOWN constant

Update Javadoc in util/src/main/java/org/hyperledger/besu/util/BesuVersionUtils.java to use {@value #UNKNOWN} instead of {@value UNKNOWN} in shortVersion() and commit() docs so the UNKNOWN field is referenced correctly. No behavioral changes.

* Use UNKNOWN constant in version regex tests

Replace hardcoded "UNKNOWN" literal in regex assertions with BesuVersionUtils.UNKNOWN constant in three unit tests (versionStringIsEthstatsFriendly, noIdentityNodeNameIsEthstatsFriendly, userIdentityNodeNameIsEthstatsFriendly) in BesuVersionUtilsTest. This keeps the tests consistent with the source constant and avoids duplicating the literal value; no behavioral change.

* Use BesuVersionUtils.UNKNOWN constant

Remove the local BESU_VERSION_UNKNOWN constant and use BesuVersionUtils.UNKNOWN instead. Simplify getRuntimeVersionString() to return BesuVersionUtils.shortVersion() directly, construct VersionMetadata with BesuVersionUtils.UNKNOWN on FileNotFoundException, and compare metadata versions against BesuVersionUtils.UNKNOWN. Centralizes the unknown-version sentinel in BesuVersionUtils.

* docs: Clarify rootCause javadoc null behavior

Update Javadoc for ExceptionUtils.rootCause to state it returns the root cause or {@code null} when the input throwable is {@code null}. This documents the method's existing behavior, which already returns null for a null input.

Signed-off-by: mykim <kimminyong2034@gmail.com>

* style: Wrap long regex in BesuVersionUtilsTest

Reformat the long regex in userIdentityNodeNameIsEthstatsFriendly test to improve readability by splitting the string across lines. This is a purely formatting change in util/src/test/java/org/hyperledger/besu/util/BesuVersionUtilsTest.java and does not alter test behavior.

Signed-off-by: mykim <kimminyong2034@gmail.com>

* chore: Use compileOnlyApi for jspecify dependency

Replace compileOnly with compileOnlyApi for org.jspecify:jspecify in util/build.gradle so jspecify annotations are exposed on the compile classpath to consumers of this module. This ensures downstream modules compiling against this artifact can see the jspecify types without packaging the dependency.

Signed-off-by: mykim <kimminyong2034@gmail.com>

* feat: Quote UNKNOWN in version regex tests

Use Pattern.quote(BesuVersionUtils.UNKNOWN) in regex assertions to ensure the UNKNOWN token is matched literally and not treated as a regex. Added import java.util.regex.Pattern and updated three assertions in BesuVersionUtilsTest (versionStringIsEthstatsFriendly, noIdentityNodeNameIsEthstatsFriendly, userIdentityNodeNameIsEthstatsFriendly) to avoid accidental regex interpretation and potential test flakiness.
