VM Options Explorer - OpenJDK25 HotSpot

Abort VM when method had failed to compile.

Call fatal if this exception is thrown. Example: 
java -XX:AbortVMOnException=java.lang.NullPointerException Foo

Call fatal if the exception pointed by AbortVMOnException 
has this message

Abort upon failure to reach safepoint (see SafepointTimeout)

Delay in milliseconds for option AbortVMOnSafepointTimeout

Abort upon failure to complete VM operation promptly

Delay in milliseconds for option AbortVMOnVMOperationTimeout

Specify the CPU count the VM should use and report as active

Adaptive size scale down factor for shrinking

Time scale over which major costs decay

Number of steps where heuristics is used before data is used

Collection interval for printing information; zero means never

Number of collections before the adaptive sizing is started

Weight given to exponential resizing, between 0 and 100

Policy for changing generation size for throughput goals

Weight given to time in adaptive policy, between 0 and 100

Increase the thread stack size to include space for glibc 
static thread-local storage (TLS) if true

Optimize heap options for long-running memory intensive apps

Control optimizations for aggressive boxing elimination

Perform vector store/load alignment in loop

Path to the directory where a temporary file will be created 
to use as the backing store for Java Heap.

Number of lines to prefetch ahead of instance allocation 
pointer

Distance to prefetch ahead of allocation pointer. 
-1: use system-specific value (automatically determined

Select instruction to prefetch ahead of allocation pointer

Number of lines to prefetch ahead of array allocation pointer

Step size in bytes of sequential prefetch instructions

0 = no prefetch, 

1 = generate prefetch instructions for each allocation, 

2 = use TLAB watermark to gate allocation prefetch, 

3 = generate one prefetch instruction per cache line

Allow Java agent to be run with CDS dumping

Allow VM to run with EXTSHM=ON.

Allow parallel defineClass requests for class loaders 
registering as parallel capable

(Deprecated) Allow redefinition to add and delete private 
static or final methods for compatibility with old releases

Application will install primary signal handlers for the JVM 
(Unix only)

Globally suppress vectorization set in VectorizeMethod

Always act like a server-class machine

Accesses to all variables should always be atomic

When using recompilation, never interpret methods 
containing loops

do all inlining incrementally

Always merge DMB instructions in code emission

Force all freshly committed pages to be pre-touched

Force java thread stacks to be fully pre-touched

Unconditionally record nmethod dependencies on class 
rewriting/transformation independently of the JVMTI 
can_{retransform/redefine}_classes capabilities.

Restore the FPU control word after every JNI call (expensive)

Force safe construction, as if all fields are final.

Always tenure objects in eden (ParallelGC only)

Cache for improving start up and warm up

Use parallel relocation code to speed up startup.

Load/link all archived classes for the boot/platform/app 
loaders before application main

The configuration file written by -XX:AOTMode=record, and 
loaded by -XX:AOTMode=create. This file contains profiling data 
for deciding what contents should be added to AOTCache.

For JVM internal testing only. The specified class is stored 
in the initialized state in the AOT cache

AOT-link JVM_CONSTANT_InvokeDynamic entries in cached 
ConstantPools
