      The jdk26ea21 build failed to start with message:
      ========================
      jdk-26/bin/java -XX:+AggressiveHeap -XX:TLABSize=64k -XX:MinTLABSize=64k -version
      OldPLABSize (8192) must be greater than or equal to ergonomic PLAB minimum size (8194)
      Error: Could not create the Java Virtual Machine.
      Error: A fatal exception has occurred. Program will exit.
      ========================
      Without "+AggressiveHeap" or with "-XX:TLABSize=32k" it works as expected.
