The algorithm is the following: * introduced a counter variable, which value can be [0-4] * if its value is 0, property hashmap allocation is enabled * JMEM_FREE_UNUSED_MEMORY_SEVERITY_LOW -> decrease the counter * JMEM_FREE_UNUSED_MEMORY_SEVERITY_HIGH -> increase the number * if JMEM_FREE_UNUSED_MEMORY_SEVERITY_HIGH happens twice in a row increase the counter to 4 According to the measurements this algorithm provides better runtime results in low memory conditions.
