You need to increase the memory size in Jdeveloper go to setDomainEnv.cmd.

set WLS_HOME=%WL_HOME%\server    
set XMS_SUN_64BIT=**256**
set XMS_SUN_32BIT=**256**
set XMX_SUN_64BIT=**3072**
set XMX_SUN_32BIT=**3072**
set XMS_JROCKIT_64BIT=**256**
set XMS_JROCKIT_32BIT=**256**
set XMX_JROCKIT_64BIT=**1024**
set XMX_JROCKIT_32BIT=**1024**

if "%JAVA_VENDOR%"=="Sun" (
    set WLS_MEM_ARGS_64BIT=**-Xms256m -Xmx512m**
    set WLS_MEM_ARGS_32BIT=**-Xms256m -Xmx512m**
) else (
    set WLS_MEM_ARGS_64BIT=**-Xms512m -Xmx512m**
    set WLS_MEM_ARGS_32BIT=**-Xms512m -Xmx512m**
)

and

set MEM_PERM_SIZE_64BIT=-XX:PermSize=**256m**
set MEM_PERM_SIZE_32BIT=-XX:PermSize=**256m**

if "%JAVA_USE_64BIT%"=="true" (
    set MEM_PERM_SIZE=%MEM_PERM_SIZE_64BIT%
) else (
    set MEM_PERM_SIZE=%MEM_PERM_SIZE_32BIT%
)

set MEM_MAX_PERM_SIZE_64BIT=-XX:MaxPermSize=**1024m**
set MEM_MAX_PERM_SIZE_32BIT=-XX:MaxPermSize=**1024m**
