Fix macOS GitHub Actions build failures#248

Conversation
Two fixes to resolve macOS build failures in CI:
1. Upgrade setup-java from v1 to v4 with Temurin distribution
- The old v1 action doesn't properly support ARM64 macOS runners
- macos-latest now uses Apple Silicon (ARM64) machines
- v4 automatically detects architecture and installs correct JDK
2. Add MAVEN_OPTS to fix JAXP XML entity size limit errors
- Set maxGeneralEntitySizeLimit, totalEntitySizeLimit, and
entityExpansionLimit to 0 to bypass XML parsing limits
- Prevents "JAXP00010004: The accumulated size of entities
exceeded the limit" errors during p2 repository parsing

Fixes #247
Summary
Problem
macOS builds were failing with two errors:
JAVA_HOME environment variable is not defined correctly- caused by setup-java v1 not supporting ARM64 macOS runners (macos-latest now uses Apple Silicon)JAXP00010004: The accumulated size of entities exceeded the limit- caused by strict XML parsing limits when loading p2 repositoriesSolution
1. Upgrade setup-java action
actions/setup-java@v1toactions/setup-java@v4architecture: x64to allow auto-detection2. Add MAVEN_OPTS environment variable
MAVEN_OPTSwith XML parsing limits disabled:-Djdk.xml.maxGeneralEntitySizeLimit=0-Djdk.xml.totalEntitySizeLimit=0-Djdk.xml.entityExpansionLimit=0Test plan
