Java API - listProcessInstances

Note: If the string '#IN_MEMORY' is appended to the moduleName, the operation returns in-memory process instances. When using the '#IN_MEMORY' option, wildcards ('*' or '?') cannot be used in the moduleName. The moduleName must either be specified in full, or left blank. (A blank moduleName returns all in-memory instances that match the specified process and/or version.)
