Enable the "Client VM emulation" mode which only uses the C1 JIT
|
||||
compiler, a 32Mb CodeCache and the Serial GC.
|
||||
The maximum amount of memory that the JVM may use (controlled by the
|
||||
\f[CB]\-XX:MaxRAM=n\f[R] flag) is set to 1GB by default.
|
||||
The string "emulated\-client" is added to the JVM version string.

||||

|
||||
.PP
|
||||
By default the flag is set to \f[CB]true\f[R] only on Windows in 32\-bit
|
||||
mode and \f[CB]false\f[R] in all other cases.
