On closer inspection, I am reverting my earlier change to `gradlew` (the one that reverted the setting of `DEFAULT_JVM_OPTS` to a 64Mbyte heap). The `gradle` launcher in gradle 7.0.1 also sets its `DEFAULT_JVM_OPTS` to a 64Mbyte heap as you can see in the following, taken from `gradle-7.0.1/bin/gradle`:


# Add default JVM options here. You can also use JAVA_OPTS and GRADLE_OPTS to pass JVM options to this script.
DEFAULT_JVM_OPTS='"-Xmx64m" "-Xms64m"'


So even though I agree that a 64 Mbyte heap is a bit on the small side, it's more important that running `gradlew` behave the same as installing gradle and running `$GRADLE_HOME/bin/gradle`. Plus I'd prefer not to maintain local modifications of this upstream script.
