| `$BPL_JVM_HEAD_ROOM` | Configure the percentage of headroom the memory calculator will allocated. Defaults to `0`. |
| `$BPL_JVM_LOADED_CLASS_COUNT` | Configure the number of classes that will be loaded at runtime. Defaults to 35% of the number of classes. |
| `$BPL_JVM_THREAD_COUNT` | Configure the number of user threads at runtime. Defaults to `250`. |
| `$BPL_JVM_CLASS_ADJUSTMENT` | Absolute or percentage based adjustment of the memory calculator's class count, which influences various memory settings of the JVM. This is useful when the number of classes cannot be reliably determined during build-time and workloads run into OOM situations. Defaults to `100%`. |
| `$BPL_HEAP_DUMP_PATH` | Configure the location for writing heap dumps in the event of an OutOfMemoryError exception. Defaults to ``, which disables writing heap dumps. The path set must be writable by the JVM process. |
| `$BPL_JMX_ENABLED` | Configure whether Java Management Extensions (JMX) is enabled. Defaults to `false`. Set this to `true` to enable JMX functionality. |
| `$BPL_JMX_PORT` | Configure the port number for JMX. Defaults to `5000`. When running the container, this value should match the port published locally, i.e. for Docker: --publish 5000:5000 |
