Line 30: {{Blockquote\|[[Sun Microsystems\|We]] intend that this specification should sufficiently document the Java Virtual Machine to make possible compatible clean-room implementations. Oracle provides tests that verify the proper operation of implementations of the Java Virtual Machine.}} The most commonly used Java virtual machine is Oracle's [[HotSpot (virtual machine)\|HotSpot]]. One of Oracle's JVMs is named HotSpot; the other, inherited from [[BEA Systems]], is [[JRockit]]. Oracle owns the Java trademark and may allow its use to certify implementation suites as fully compatible with Oracle's specification.▼ ▲~~One of Oracle's JVMs is named HotSpot; the other, inherited from [[BEA Systems]], is [[JRockit]].~~ Oracle owns the Java trademark and may allow its use to certify implementation suites as fully compatible with Oracle's specification. ===Garbage collectors=== Line 39 ⟶ 41: !
