Drools Flow execution with single RuleSet node (besides Start and Stop nodes) results with no ruleset rules execution and java.lang.OutOfMemoryError.

Trying to invoke drools flow with single RuleSet element only (besides Start/Stop elems) results in java.lang.OutOfMemoryError: GC overhead limit exceeded.
Also this bug affects probably all flows, with RuleSet element as first in execution flow.
See stacktrace
